Introduction

Few issues frustrate pool owners as much as recurring algae. While green algae is common and usually responds well to chlorine, mustard algea is far more stubborn. This yellowish growth clings to walls, steps, and shaded areas, often reappearing even after brushing and shocking. For many pool owners, this leads to endless cycles of cleaning, spending on chemicals, and disappointment.

The persistent nature of mustard algae makes it one of the most challenging problems in pool maintenance. Unlike its green counterpart that typically responds to standard chlorine treatments, mustard algae has developed sophisticated survival mechanisms that allow it to withstand normal sanitizer levels. This resilience transforms what should be a simple maintenance issue into an ongoing battle that tests both patience and pool care budgets.

The big question is: can a solar pool ionizer help prevent and control mustard algae in pool systems? The short answer is yes, but effectiveness depends on proper setup and consistent maintenance. Solar ionizers represent an innovative approach to pool sanitation that complements traditional chemical methods, offering continuous protection against algae growth through natural mineral ionization. However, their success in combating stubborn mustard algae requires understanding both the technology and the unique characteristics of this particular algae type.

In this comprehensive guide, we'll explore what mustard algae really is, why it's so difficult to control, and how a solar ionizer fits into an overall algae-prevention strategy. We'll examine the science behind ionization technology, provide detailed step-by-step instructions for implementation, and discuss how to integrate solar ionizers with other pool maintenance practices for maximum effectiveness against this persistent aquatic pest.

What Is Mustard Algae?

Mustard algae, also known as yellow algae, is a chlorine-resistant cousin of green algae. It appears as dusty yellow or brownish patches on walls, ladders, and pool equipment. At first glance, it can be mistaken for dirt or sand, but unlike debris that vacuums up easily, it clings tightly to surfaces and often returns quickly.

Scientifically classified as a type of green algae (Chlorophyta), mustard algae (Phaeophyta) has evolved specific adaptations that make it particularly troublesome for pool owners. Its characteristic yellow-brown coloration comes from the presence of fucoxanthin, a pigment that helps the algae absorb different wavelengths of light than typical green algae. This pigment also contributes to its chlorine resistance by creating a protective barrier around the algal cells.

Unlike green algae that floats in the water, mustard algae in pool water forms biofilms that protect it from chlorine and other sanitizers. These biofilms are complex communities of microorganisms encased in a protective polymeric substance that acts as a shield against chemical treatments. The biofilm structure allows mustard algae to establish colonies in areas with minimal water circulation, where chemical concentrations are typically lower and the algae can grow undisturbed.

Even after shocking, spores can survive in hidden corners, on brushes, pool toys, or swimsuits. Mustard algae produces highly resilient spores that can remain dormant for extended periods, waiting for favorable conditions to germinate. These spores have thick protective walls that make them resistant to drying, temperature fluctuations, and chemical exposure. This resilience is why many pool owners struggle with recurring outbreaks, as spores can be reintroduced to the pool from previously contaminated equipment or swimwear.

The tenacious nature of mustard algae means that complete eradication requires a comprehensive approach that addresses both visible growth and hidden spores. Understanding its biological characteristics and survival strategies is the first step toward developing an effective control strategy that prevents the cycle of treatment and re-infestation that frustrates so many pool owners.

Why Mustard Algea Is a Problem

Mustard algae doesn't just make your pool look dirty; it creates serious pool maintenance challenges that can affect both the pool's operation and the swimming experience. The problems extend far beyond mere aesthetics, impacting filtration efficiency, chemical consumption, and overall pool health.

Clogs filters: Colonies multiply and clog cartridge or DE filters, reducing efficiency. As mustard algae colonies grow and break apart, the particles are small enough to pass through initial filtration but accumulate in filter media over time. This accumulation creates a dense mat that restricts water flow, increases pressure in the filtration system, and reduces the filter's ability to capture other contaminants. The result is a gradual decline in water clarity and increased strain on the pool pump as it works harder to move water through the clogged filter.

Blocks skimmers: Floating particles and colonies can obstruct skimmer baskets, making circulation less effective. Mustard algae often forms floating mats or releases individual cells that get drawn into the skimmer system. These organic masses can completely block skimmer baskets, preventing proper surface cleaning and reducing the skimmer's ability to remove other debris like leaves and insects. This blockage creates a cascade effect where poor skimming leads to more organic material in the pool, which in turn provides more nutrients for algae growth.

Releases odors: Advanced blooms can release unpleasant smells, discouraging use. As mustard algae colonies die and decompose, they release volatile organic compounds that create distinctive musty, earthy odors. These odors can permeate pool areas and cling to swimwear and equipment. The smell is particularly noticeable when the pool cover is removed or when the water is disturbed during swimming, creating an unpleasant environment that diminishes the enjoyment of using the pool.

Spreads fast: Spores can cling to swimsuits and transfer between pools. Mustard algae produces microscopic spores with sticky surfaces that easily adhere to fabrics, plastic, and other materials. When contaminated items are moved between pools or stored and reused, they introduce the algae to new environments. This cross-contamination risk means that a single infected swimsuit or pool toy can introduce mustard algae to previously clean pools, making community spread a significant concern in neighborhoods with multiple pool owners.

Chlorine resistance: Even after shocking, mustard algae can regrow in less than 24 hours if conditions remain favorable. Mustard algae has developed multiple resistance mechanisms that allow it to survive chlorine levels that would eliminate other algae types. These include protective biofilms, spore formation, and cellular repair mechanisms that activate after chemical exposure. This rapid recovery capability means that pool owners often see algae returning almost immediately after treatment, leading to frustration and repeated chemical applications that increase maintenance costs and environmental impact.

Without proper algae control, mustard algae can take over quickly, forcing repeated treatments and increasing costs. The cumulative effect of these problems transforms pool maintenance from a routine task into a constant battle, consuming time, money, and enjoyment. Understanding the full scope of challenges posed by mustard algae underscores the importance of comprehensive control strategies that address both immediate growth and long-term prevention.

How Solar Pool Ionizers Work

A solar pool ionizer is a floating device powered by sunlight. It uses a solar panel to generate energy, which then releases copper, silver, and sometimes zinc ions into the water. These minerals act as natural algaecides and bactericides, providing continuous protection against microbial growth through an electrochemical process that mimics natural water purification methods.

The technology behind solar ionizers represents an innovative approach to pool sanitation that harnesses natural elements rather than relying solely on synthetic chemicals. The device typically consists of a floating housing containing a small solar panel, a control circuit, and electrode chambers where the ionization process occurs. When sunlight strikes the solar panel, it generates a low-voltage electrical current that powers the ionization chambers.

Copper ions damage algae cells, preventing photosynthesis and growth. When copper ions enter algae cells, they disrupt multiple cellular processes including photosynthesis, respiration, and nutrient transport. The ions interfere with enzyme systems, damage cell membranes, and prevent cell division. This multi-target approach makes it difficult for algae to develop resistance, as surviving cells would need to evolve protection against multiple simultaneous attacks. The copper concentration required for effectiveness is remarkably low typically between 0.2 and 0.4 parts per million - making it safe for swimmers while still lethal to algae.

Silver ions attack bacteria, preventing them from forming protective biofilms around algae. Silver ions are particularly effective against the bacteria that often form symbiotic relationships with algae, helping to create the protective biofilms that make mustard algae so resistant to conventional treatments. The silver ions bind to bacterial cell walls, causing structural damage and increased permeability. Inside the cells, they interfere with metabolic processes and DNA replication. By controlling the bacterial component of algae ecosystems, silver ions help break down the protective structures that allow mustard algae to survive chemical treatments.

Zinc ions stabilize water and improve overall clarity. While not always included in ionizer systems, zinc provides additional benefits when present. Zinc ions help control scale formation by interfering with calcium carbonate crystallization, reducing the buildup that can provide additional attachment points for algae. They also contribute to water clarity by helping to coagulate fine particles, making them large enough to be captured by the filtration system. This multi-mineral approach creates a comprehensive water treatment system that addresses multiple aspects of pool water quality simultaneously.

Since the device floats on the surface, it works continuously whenever sunlight is present, requiring minimal intervention from the pool owner. The floating design ensures optimal sunlight exposure for the solar panel while allowing the released ions to distribute naturally through the water as the device moves with circulation patterns. This continuous operation means protection is maintained throughout daylight hours, with some systems incorporating battery backup or capacitor storage to extend operation during brief cloudy periods. The autonomous nature of solar ionizers makes them an ideal "set and forget" component of a comprehensive pool maintenance strategy.

Can a Solar Ionizer Help With Mustard Algae?

Yes, solar pool ionizers can significantly reduce the risk of mustard algae pool infestations. By constantly releasing minerals, they create an environment where algae spores struggle to survive. The continuous presence of copper and silver ions in the water provides ongoing protection that complements periodic chemical treatments, addressing the fundamental challenge of mustard algae management. Its ability to quickly regrow after traditional treatments have dissipated.

The effectiveness of solar ionizers against mustard algae stems from their ability to maintain a constant low level of algaecide in the water. Unlike shock treatments that create a high concentration that rapidly declines, ionizers provide steady mineral release that prevents the window of opportunity algae spores need to establish new colonies. This continuous protection is particularly valuable during the critical 24-48 hour period after shocking when algae spores are most vulnerable but traditional chlorine levels are dropping rapidly.

However, because mustard algae is more resistant than green algae, an ionizer alone may not completely eliminate it. Mustard algae's protective biofilms and spore-forming capabilities mean that established infestations require aggressive initial treatment before ionizers can provide effective ongoing protection. The ionizer's mineral ions work best against free-floating cells and newly germinating spores rather than established colonies with mature protective structures.

Instead, think of the ionizer as a preventive tool. Once you've killed existing colonies using shock and brushing, the ionizer helps keep algae from returning. This strategic approach recognizes that different tools are needed for different phases of algae control aggressive chemical treatments for elimination and continuous ionization for prevention. The ionizer serves as a maintenance tool that extends the effectiveness of your initial treatment, much like a security system that protects a building after the initial break-in has been addressed.

This is especially useful after the first 24 hours post-treatment, when spores typically attempt to regrow. The period immediately following shock treatment represents a critical vulnerability window when chlorine levels are declining but algae spores are activating. Solar ionizers bridge this gap by maintaining protective mineral levels that inhibit spore germination and colony formation. This continuous protection is particularly valuable for pool owners who cannot maintain perfect chemical balance at all times or who experience fluctuating environmental conditions that favor algae growth.

The key to success with solar ionizers against mustard algae lies in understanding their role within a comprehensive management strategy. They are not a standalone solution for established infestations but rather an invaluable component of a multi-faceted approach that includes proper filtration, regular maintenance, and appropriate chemical support. When used correctly, they can significantly reduce the frequency and intensity of mustard algae outbreaks, transforming a constant battle into manageable maintenance.

Step-by-Step Guide: Using a Solar Ionizer Against Mustard Algea

1. Identify the Problem: 

Confirm you're dealing with mustard algae. Look for yellow, dusty patches that resemble dirt or sand, often in shaded areas. Proper identification is crucial because different algae types require different treatment approaches. Mustard algae typically appears as yellowish-brown or tan patches that have a powdery or silt-like texture. Unlike dirt or pollen that brushes away easily, mustard algae will feel slightly slimy and will cling to surfaces. It frequently establishes in areas with poor circulation behind ladders, in corners, on steps, and along the waterline in shaded sections of the pool. To confirm mustard algae, perform a simple test: brush the suspected area and observe if the material clouds the water with a yellow or brown tint. If the cloudiness persists and settles back in the same pattern, you're likely dealing with mustard algae rather than ordinary debris.

2. Brush Thoroughly:

Use a stiff pool brush to scrub walls, ladders, and steps. Brushing breaks algae's grip and exposes it to sanitizers. Brushing is perhaps the most critical step in mustard algae control because it disrupts the protective biofilms that make this algae so resistant to treatment. Use a stiff-bristled brush for concrete or plaster pools, or a nylon brush for vinyl or fiberglass surfaces to avoid damage. Brush all pool surfaces systematically, paying special attention to areas where mustard algae typically hides. Brush from the shallow end toward the deep end, using overlapping strokes to ensure complete coverage. For severe infestations, you may need to brush multiple times during the treatment process. The mechanical action of brushing serves two important purposes: it physically removes algae from surfaces, and it breaks open protective layers so chemicals can penetrate more effectively.

3. Shock the Pool:

Apply a chlorine shock at 2–3 times the normal dose. Maintain high chlorine for at least 24 hours to weaken the algae. Mustard algae's chlorine resistance necessitates aggressive shock treatment. Use a chlorine-based shock product and calculate the dosage based on 2-3 times the normal amount for your pool volume. For example, if your pool normally requires 1 pound of shock per 10,000 gallons, use 2-3 pounds for mustard algae treatment. Dissolve the shock in a bucket of water before adding it to the pool to ensure even distribution. Add the shock in the evening to minimize chlorine loss from sunlight, and run the pump continuously to maintain circulation. Test chlorine levels after 2-3 hours and again after 12 hours to ensure they remain elevated. The goal is to maintain a chlorine level of 10-15 ppm for at least 24 hours to penetrate the algae's defenses and kill both active colonies and vulnerable spores.

4. Vacuum and Clean: 

Vacuum debris, paying special attention to shady spots where mustard algae hides. Wash pool toys and swimsuits to avoid recontamination. After shocking and brushing, vacuum the pool thoroughly to remove dead algae and debris. Use a slow, methodical vacuuming pattern with overlapping passes to ensure complete coverage. Pay special attention to areas where mustard algae was most prevalent. If possible, vacuum to waste to prevent dead algae from passing through your filter system. If you must vacuum through the filter, be prepared to clean or backwash the filter immediately afterward. Simultaneously, remove and thoroughly clean all pool equipment, brushes, nets, toys, floats, and vacuum heads. Wash swimsuits that have been in the infected pool with hot water and bleach or a specialized algae-killing detergent. This comprehensive cleaning prevents recontamination from spores hiding on equipment and accessories.

5. Add Solar Pool Ionizer:

Place the ionizer in a sunny spot. It will begin releasing ions that help prevent new algae growth. Once the initial aggressive treatment is complete, introduce the solar ionizer as a preventive measure. Choose a location where the device will receive maximum sunlight exposure throughout the day, typically in the center of the pool or in an area unobstructed by shadows from trees or structures. Ensure the ionizer can move freely with water currents to promote even distribution of ions. Follow the manufacturer's instructions for initial setup, which may include priming the electrodes or setting specific operational parameters. The ionizer will begin working immediately when exposed to sunlight, establishing a baseline level of copper and silver ions that will help prevent new algae growth and inhibit any surviving spores from developing into new colonies.

6. Monitor Copper Levels: 

Use test strips to ensure copper stays between 0.2–0.3 ppm. Too much can stain pool surfaces. Regular monitoring of copper levels is essential for both effectiveness and safety. Use test strips specifically designed for copper measurement, checking levels at least once per week during the initial treatment period and every 2-3 weeks thereafter for maintenance. The ideal range for algae control is 0.2-0.3 parts per million (ppm). Levels below this range may not provide adequate protection, while levels above 0.4 ppm increase the risk of staining on pool surfaces and equipment. If copper levels become too high, you may need to remove the ionizer temporarily or perform a partial water change. Keep records of your test results to identify patterns and make adjustments to your maintenance routine as needed.

7. Maintain Circulation:

Run the pump for at least 8–12 hours daily. Proper circulation helps distribute ions evenly. Effective circulation is crucial for both algae prevention and ionizer performance. Run your pool pump for a minimum of 8-12 hours per day, increasing to 12-16 hours during periods of heavy use, extreme heat, or active algae treatment. Proper circulation ensures that the ions released by the solar ionizer are distributed evenly throughout the pool, reaching all areas where algae might attempt to establish. Check that return jets are positioned to create good circular flow without dead spots. Periodically verify that skimmer and pump baskets are clean and unobstructed. Good circulation not only distributes treatment chemicals but also prevents the stagnant conditions that algae favor for growth.

8. Repeat Brushing and Shock as Needed: 

For heavy infestations, repeat the process until algae is fully gone. Mustard algae's resilience often requires repeated treatments for complete eradication. If you notice algae returning after the initial treatment, repeat the brushing and shock process. For persistent cases, you may need to maintain elevated chlorine levels for 48-72 hours rather than just 24 hours. Some pool professionals recommend a "shock and maintain" approach where you shock the pool initially, then add smaller maintenance doses of shock every 12 hours for 2-3 days to ensure complete elimination. Between chemical treatments, continue brushing affected areas daily to disrupt new growth. The solar ionizer will become increasingly effective as the algae population decreases, providing ongoing protection that helps prevent recurrence once the active infestation is under control.

Benefits of Combining Ionizers With Other Methods

While ionizers provide long-term defense, they work best as part of a complete strategy that addresses all aspects of pool water quality and maintenance. The integrated approach recognizes that no single solution can effectively manage mustard algae given its adaptive capabilities and resilience. Combining methods creates multiple barriers that algae must overcome, significantly reducing the likelihood of successful establishment and spread.

Balanced water chemistry: Keep pH at 7.2–7.8 and chlorine at 1–3 ppm. Unbalanced water fuels algae growth. Proper water balance is the foundation of effective algae control. When pH is within the ideal range, chlorine is significantly more effective as a sanitizer. Test and adjust water chemistry at least weekly, paying attention to pH, alkalinity, and chlorine levels. Imbalanced water not only reduces chemical effectiveness but can also create conditions that directly promote algae growth. For example, high pH reduces chlorine's killing power, while low pH can corrode equipment and surfaces. The solar ionizer works most effectively when water chemistry is properly balanced, as extreme pH levels can affect ionization rates and mineral solubility.

Regular brushing: Prevents spores from settling back into crevices. Brushing should be part of your weekly maintenance routine, even when no visible algae is present. Regular brushing disrupts microscopic algae spores before they can establish colonies and removes the biofilm precursors that protect developing algae. Focus on areas with poor circulation and shaded spots where mustard algae typically first appears. Combining regular brushing with ionization creates a powerful physical-chemical barrier. Brushing removes attached spores while ionization kills free-floating ones. This combination is particularly effective because it addresses algae at different stages of their life cycle and in different locations within the pool.

Filter maintenance: Backwash or clean filters often to avoid clogging. Your filtration system is your primary mechanical defense against algae and other contaminants. Clean or backwash filters according to manufacturer recommendations, typically when pressure rises 8-10 psi above clean pressure. For mustard algae specifically, you may need more frequent filter cleaning during active treatment periods because dead algae cells can quickly clog filter media. A clean filter not only removes algae particles more effectively but also maintains proper circulation that supports even chemical and ion distribution. Consider adding a filter cleaner specifically designed to remove organic buildup, which can harbor algae spores and reduce filtration efficiency.

Algaecides: Consider occasional use of a mustard-algae-specific algaecide if outbreaks persist. While the goal is to minimize chemical use, sometimes targeted algaecide application is necessary for stubborn mustard algae. Look for algaecides specifically labeled for mustard algae, which typically contain ingredients designed to penetrate the algae's protective barriers. Use these products as spot treatments or for periodic preventative doses rather than continuous application. When using algaecides alongside a solar ionizer, be aware of potential interactions. Some algaecides may contain metals that could contribute to staining if copper levels become too high. Always follow label instructions and consider consulting a pool professional for persistent algae problems.

This multi-layered approach ensures that your mustard algae pool stays clean, clear, and swim-ready. Each component addresses different vulnerabilities in the algae's life cycle and habitat requirements, creating a comprehensive defense system that is much more effective than any single method alone. The solar ionizer provides continuous background protection, while the other methods address specific challenges as they arise. This integrated strategy not only controls existing algae but also creates an environment that is inherently resistant to new infestations, transforming pool maintenance from reactive problem-solving to proactive prevention.

Additional Benefits of Solar Pool Ionizers

Beyond tackling algae, solar ionizers offer other advantages that enhance overall pool management and improve the swimming experience. These additional benefits make them a valuable investment beyond their primary role in algae control, contributing to easier maintenance, reduced environmental impact, and better water quality.

Eco-friendly: Runs on sunlight, reducing reliance on chemicals. Solar ionizers operate entirely on renewable solar energy, eliminating electricity consumption and reducing the carbon footprint associated with pool maintenance. By providing continuous algae protection, they significantly reduce the need for chemical algaecides, many of which contain synthetic compounds that can persist in the environment. The copper and silver ions used in ionization are natural elements that occur in the environment and break down more readily than many synthetic chemicals. This environmental benefit extends beyond the immediate pool area to broader ecosystem impacts, as reduced chemical use means fewer compounds entering wastewater systems or being released into the environment during backwashing or drainage.

Lower chlorine use: Helps maintain lower chlorine levels without risking algae growth. The continuous algae protection provided by solar ionizers allows pool owners to maintain chlorine at the lower end of the recommended range (1-2 ppm rather than 2-4 ppm) while still preventing algae growth. This reduction in chlorine use has multiple benefits: it lowers chemical costs, reduces chlorine odor that many swimmers find unpleasant, and minimizes the skin and eye irritation associated with higher chlorine levels. Lower chlorine levels also reduce the formation of chloramines chemical compounds created when chlorine combines with swimmer waste that cause the distinctive "chlorine smell" and can irritate mucous membranes. The result is a more comfortable swimming environment that feels more like natural water than a heavily treated pool.

Prevents staining and scale: Ions reduce calcium buildup and organic stains. The mineral ions released by solar ionizers help prevent several common pool surface problems. Copper ions inhibit the growth of algae and other microorganisms that can cause organic staining on pool surfaces. Silver ions control bacteria that contribute to biofilm formation, which can trap dirt and minerals against pool surfaces. Some ionizer systems also include zinc, which interferes with calcium carbonate crystallization, reducing scale formation on tiles, equipment, and pool surfaces. This protective effect helps maintain the appearance and longevity of pool finishes and equipment, potentially saving significant money on surface repairs and equipment replacement over the life of the pool.

Low maintenance: Only requires occasional cleaning of electrode plates. Unlike many pool systems that require regular adjustment, refilling, or complex maintenance, solar ionizers are remarkably low-maintenance. The primary maintenance requirement is occasional cleaning of the electrode plates to remove mineral scale that can reduce ionization efficiency. This cleaning typically involves removing the ionizer from the pool, opening the electrode chamber, and gently brushing or soaking the plates to remove deposits. Depending on water hardness and usage, this may only be necessary every 2-4 months. The solar-powered operation means no electrical connections, timers to set, or batteries to replace. This simplicity makes solar ionizers an ideal solution for pool owners who want effective algae control without adding complexity to their maintenance routine.

By integrating this tool into your pool maintenance routine, you not only fight algae but also improve overall water quality. The cumulative benefits create a pool that is easier to maintain, more pleasant to use, and better for the environment. While the initial investment in a solar ionizer may be higher than traditional chemical algaecides, the long-term savings in reduced chemical use, fewer maintenance problems, and extended equipment life often make them a cost-effective choice over time. More importantly, they contribute to a swimming experience that feels more natural and less chemically treated, enhancing the enjoyment of your pool throughout the swimming season.

Conclusion

Dealing with mustard algea is one of the toughest challenges in pool care. It masquerades as dirt or sand, resists chlorine, and often returns within 24 hours if not handled correctly. The unique characteristics of mustard algae its protective biofilms, spore-forming capability, and chlorine resistance make it a formidable opponent that requires a sophisticated approach rather than simple chemical applications. Many pool owners find themselves in a frustrating cycle of treatment and re-infestation that consumes time, money, and the simple pleasure of having a clean, inviting pool.

But with a combination of proper brushing, shocking, balanced water chemistry, and the ongoing support of a solar pool ionizer, you can gain the upper hand. This comprehensive approach addresses mustard algae at multiple points in its life cycle and through different control mechanisms. The aggressive initial treatment eliminates established colonies, while the ongoing ionization provides continuous protection against new growth. The supporting practices of proper filtration, regular brushing, and balanced water chemistry create an environment that is inherently resistant to algae establishment.

While the ionizer won't cure a full-blown outbreak on its own, it plays a critical role in preventing mustard algae in pool systems from returning. This distinction between treatment and prevention is crucial for long-term success. Solar ionizers excel as maintenance tools that extend the effectiveness of initial treatments and provide ongoing protection that chemical methods cannot match due to their fluctuating concentration levels. The continuous, low-level mineral release creates a persistent hostile environment for algae while remaining safe for swimmers and gentle on pool equipment.

For long-term clarity and healthier water, pair your solar ionizer with strong pool maintenance habits and enjoy a cleaner, more inviting swimming experience. The investment in a solar ionizer represents a shift from reactive to proactive pool care, where the goal is prevention rather than repeated treatment. This approach not only saves time and money but also creates a more enjoyable pool environment with reduced chemical odors, less irritation, and water that feels more natural. By understanding the role of each component in your algae control strategy and implementing them consistently, you can transform mustard algae from a persistent problem into a manageable maintenance consideration, freeing you to focus on enjoying your pool rather than constantly fighting to keep it clean.
