Solar-powered pool care

Use up to 80% less chlorine in your pool

It floats. It runs on sunlight. It releases copper ions that hold algae back all season - so your chlorine has far less work to do. No wiring, no plumbing, nothing to install.

The problem

Most of your chlorine isn't sanitizing swimmers

It's fighting algae. Take that job away from chlorine and you need far less of it.

Chlorine alone

  • Burns off fastest in heat and sun - exactly when algae grows quickest
  • A trip to the pool store every other week, all season
  • Red eyes, dry skin, bleached swimsuits, that heavy smell on towels
  • One hot weekend away and you come home to a green pool
  • High levels wear out liners, o-rings and pump seals over time

Chlorine + a solar ionizer

  • Copper ions work continuously through daylight - they don't burn off at midday
  • Most owners run about 1 ppm instead of 3
  • Noticeably softer water, far less smell and irritation
  • A steady baseline that closes the gap between chlorine doses
  • Five minutes of upkeep every couple of weeks - brush the anode, that's it

How it works

Four steps, then it looks after itself

No wiring, no plumbing, no controller to program.

1

Drop it in

Attach the copper anode and set the unit in your pool, away from the skimmer.

2

Sunlight starts it

The solar panel converts daylight into a low current. It switches on at sunrise by itself.

3

Copper ions release

That current releases copper ions from the anode at a slow, controlled rate.

4

Algae stops growing

Copper interferes with algae's ability to reproduce - so your chlorine dose drops.

Choose your size

Two models, sized by water volume

Getting the size right matters more than anything else - an undersized unit can't hold copper level in peak summer.

What it does and what it doesn't

A solar ionizer reduces how much chlorine your pool needs. It does not replace it. Copper suppresses algae; it doesn't sanitize fast enough to keep swimmers safe on its own, so you still keep a small chlorine residual - most owners run around 1 ppm instead of 3.

Anyone selling you a completely chemical-free pool is selling you a green one by August. We'd rather you hear that now than discover it in July.

You'll also need to do two small things: test copper weekly with the included strips and keep it between 0.2 and 0.4 ppm, and brush the anode every couple of weeks so scale doesn't block it. That's about five minutes a fortnight. Do those and the unit works all season. Skip them and it won't.

From pool owners

What customers say after a season

Reviews from people who've actually run the unit - not unboxings.

★★★★★

Use less chlorine and keep your water clear. Solar powered, so just let it float in the sun. Comes with testing strips to check your levels and a brush to clean the copper - you must clean the copper to make sure it works properly.

This device extends the cleaning of my pool water for a longer period of time and reduces the amount of chlorine tablets I have to use for maintenance. I like it very much.

Placeholder - swap in a review describing a full season of use. Ideally one that names a specific pool size and says how much the chlorine dose dropped.

Keep it working

The anode is a consumable and that's by design

The copper anode dissolves slowly. That's the mechanism. Under typical use it lasts a full swim season, then a replacement kit restores the unit to full output.

  • Everything in one kit - anode, basket screen, spring and screw
  • Takes about two minutes to swap
  • Brush the anode first - scale makes a good anode look dead
  • From $62.95 - about a quarter of a season's chemicals

Questions

Before you buy

Will this completely replace chlorine?

No. It reduces chlorine demand substantially - up to 80% for most owners, but a pool with no sanitizer isn't safe to swim in. Expect to run about 1 ppm instead of 3.

How long does the copper anode last?

Typically one full swim season. Strong sun, warm water and larger pools wear it faster. Before replacing one, brush it - scale buildup blocks ion release and makes a perfectly good anode look dead.

Will it stain my pool or turn hair green?

Not at the recommended level. Keep copper between 0.2 and 0.4 ppm and test weekly with the included strips. Staining and green tinting come from over-ionizing - pull the unit out if you go above 0.5 ppm.

Does it work on cloudy days or at night?

It produces less on overcast days and nothing at night - output tracks sunlight. That's why you test copper rather than assume.

Can I use it in a pond with fish?

No. Copper is toxic to fish, snails and shrimp at levels far below what this unit produces. Use it in swimming pools and spas only - never in a pond, koi feature or any water containing aquatic life.

Does it work with a saltwater pool?

Yes. It reduces the load on your salt cell, which extends cell life. It also works with in-ground, above-ground, vinyl and fiberglass pools.

Do I leave it in over winter?

No. Remove it before closing, rinse and dry the anode, and store it indoors. Freezing water can crack the housing.

Fewer chemicals. Clearer water.
Same pool.

Free shipping, and 90 days to try it in your own pool. If your water isn't clearer and your chlorine bill isn't lower, send it back.
