Why is My Pool Water Green?
Your swimming pool is suffering from green algae growth. A common free-floating variety of algae imparts a cloudy green color to pool water. It’s easy to correct if treated early. Shock your pool, then use the proper dose of algaecide for the size of your pool.
Your pool may also be experiencing low total alkalinity, which can contribute to green algae growth, so you may also need to add an alkalinity increaser.
What do I do now?
Follow the instructions below for the best results.
- Remove most of the large debris from the pool floor with a large leaf net (not a hand skimmer!).
- Adjust the pH and Alkalinity levels of the water using pH Plus, pH Minus and Alkalinity Plus.
- Shock the pool. This means super chlorinating the water to kill off any bacteria and algae.
- Run your filter 24 hours a day and backwash 3 or 4 times a day for quickest results.
If you follow these instructions and your pool does not clear up within 4 or 5 days, your filter may not be functioning properly. If this is the case with your pool, have the filter system checked out by a professional.

We went on a week long vacation and when we came back home our pool was completely green! I think my pool pump failed a few days after we left. We quickly contacted Ramon from Ramon Pool Service, LLC. and he replaced the pool pump. He treated the pool water and we had our beautiful crystalline blue water in a few days.
The most common cause for a green pool is the pool pump failure. In the summer it just takes a couple of days for your pool to turn green.
