Pro Tips for Maximum Effectiveness

Expert Tips from Pool Professionals

• Start early: Begin using at pool opening for season long protection
• Be consistent: Weekly application is key to prevention
• Maintain chlorine: Algaecide works with chlorine, not instead of it
• Balance chemistry first: Proper pH ensures optimal algaecide performance
• Don't skip weeks: Consistency prevents algae breakthrough
• Add after rain: Extra dose after storms prevents algae blooms
• Brush regularly: Brushing helps distribute algaecide and prevents algae attachment
• Monitor copper levels: Test monthly to prevent staining
• Measure carefully: Very small doses required due to high concentration
• Practice eco-friendly methods: Learn eco-friendly pool cleaning practices

Avoid Common Mistakes

• Overdosing: More is not better, can cause staining
• Skipping weekly doses: Inconsistent use allows algae breakthrough
• Not maintaining chlorine: Algaecide supplements chlorine, doesn't replace it
• Ignoring water balance: Poor chemistry reduces algaecide effectiveness
• Adding to skimmer: Always add around pool perimeter
• Not brushing: Brushing helps prevent algae attachment
• Using with low pH: Can increase staining risk
• Not testing copper: High copper can cause staining

Preventing Copper Staining

Best Practices:

• Follow dosage guidelines precisely
• Maintain pH between 7.2 and 7.6
• Don't overdose algaecide
• Test copper levels monthly (keep below 0.5 ppm)
• Use metal sequestrant if copper levels are high
• Avoid shocking immediately after adding algaecide
• Ensure proper water circulation

Maximizing Algaecide Performance

Water Chemistry: Maintain proper balance for optimal algaecide performance. pH between 7.2 and 7.6 is critical.

Chlorine Levels: Keep chlorine at 1 to 3 ppm. Algaecide works with chlorine for complete protection.

Circulation: Good water circulation ensures algaecide reaches all areas of pool.

Prevention: Weekly use prevents algae more effectively than treating existing blooms.

Troubleshooting Common Issues
