Previous Troubleshooting Tip: Clear Green Water

There are a few things that can cause cloudy water in your pool or spa. Let’s investigate.

• Check ​ the filter system for malfunction; the filter may be plugged up or it may need chemical cleaning, usually indicated by filter pressure above 20 pounds per square inch (psi)
• Check the filter; it could have holes that are letting fine particles pass through it
• Check your pump to make sure it is operating effectively
• Check your filtration system and lines
• Make sure you are running the filter long enough to clean your pool
• Air could be trapped in your filtration system; usually indicated with 0 psi or a very low filter pressure or lack of water flow
• Your water level could be too low, preventing proper flow
• Next, test water for total alkalinity and pH or hardness levels; these levels may be too high
• Check the water for low chlorine level and check for presence of dead algae
• For help with a specific question, you can call our free helpline at 1-800-SOS-POOL (767-7665)

• After you fix the cause, shock the water with one of our Step One shock products
