With heavy rainfall, the chemicals in your pool can become unbalanced; your pH levels altered and your chlorine, salt and mineral content diluted. In addition, leaves, dirt and algae spores get delivered into your pool water and can decompose, causing phosphates to be deposited into your water. Pools situated close to farm fields are particularly exposed to agricultural mineral contamination. Combined with sunlight, these conditions are perfect for algae and other contaminants to grow and affect the health of your pool, turning it green overnight.
If your pool has turned green after a rainstorm, it could be because there are algae growing in your pool water. If this is the case, please visit our section on Green Water Cleanup.
Fixing a Green Pool
Before beginning any post-rain storm pool cleaning, ensure you do the following:
- Empty skimmer and pump baskets. If you don’t the accumulated debris in the pool will clog the baskets and reduce the flow of water. Baskets may burst and need to be replaced.
- Remove large debris and leaves from the water. They will influence the water chemistry of the pool and potentially stain your pool’s surface.
- Test your pool water. See our section on Pool Maintenance.
C-Pool and Spa Algaecidal features
This advice is for pools that have a green tinge to the water and algae on the walls. With heavy rainfall, the chemicals in your pool can become unbalanced; your pH levels altered and your chlorine, salt and mineral content diluted.

If your pool has turned green after a rainstorm, consider C-PoolandSpa. This works in conjunction with your chlorine, salt and minerals to quickly and more effectively kill the algae in your pool, bringing your pool back from green to clean. Clean your pool up first.
Organic material in the pool consumes algaecide, making it less effective. Make sure you run your filter with the C-Pool.
This helps to disperse the natural minerals and remove the suspended matter. C-Pool has little impact on stagnant water.

Tips on using C-PoolandSpa:
- Clean your pool up first. Organic material in the pool consumes both chlorine and algaecide, making them less effective.
- Make sure you run your filter with the C-Pool minerals broadcasted over the water surface.
- This helps to disperse the minerals and capture and remove the suspended matter.
