Algae can start fast, especially during warm weather. Once it spreads, cleanup becomes more labor-intensive and more expensive than routine prevention.
What causes algae growth
- Low sanitizer levels
- Poor circulation
- Dirty filters or baskets
- Unbalanced chemistry
- Debris left sitting in the pool
Simple prevention habits
- Keep up with weekly testing and chemical balancing
- Brush walls, steps, and corners where algae can begin
- Make sure the filter and pump are working properly
- Remove leaves and debris quickly
- Address cloudy water early before it worsens
If you notice slippery surfaces, green dust, or recurring algae despite chemical additions, it may be time for a full inspection of both chemistry and equipment.
