Swimming pools can be relaxing and fun. But sometimes the water becomes foggy and cloudy, which can discourage you from enjoying your pool. Here are instructions on how to clear cloudy pool water.
To clear cloudy pool water, you may need to use some chemicals. For any products you use, be sure to read the label directions carefully for specific instructions on how to use the product correctly and safely. In addition, pool experts recommend that you:Store products in their original containers in a cool, dry and well-ventilated area out of the reach and sight of small children.Never smoke while using pool chemicals.Always add chemicals to the water — never add water to the chemicals.Never add chemicals to the pool while someone is in the water.Never mix chemicals unless the label specifically instructs you to do so.Always wear rubber gloves when handling chemicals.
Solving Cloudy Water Problems
Cloudy water in swimming pools can be caused by poor filtration, pH imbalance or inadequate chlorine levels.Step 1
Refer to the pool filter manufacturer’s directions to:
- Make sure the filtration system is running for the amount of time adequate to clarify water based on the pool size and use.
- Backwash the filtration system as recommended. Backwashing is the process of reversing the water flow back through the filter to remove debris.
- Chemically clean the filter with a filter cleaner on a regular basis, as recommended by the manufacturer.
Use a pool water test kit or test strips to check the pH level of the water.
- Cloudy water can be caused by high pH levels. The pH should be between 7.2 and 7.6. Total alkalinity should be around 80 to 125 parts per million (ppm) for plaster / gunite pools and 125 to 150 ppm for all other pool types.
- Pool water test kits are available at Lowe’s.
Add any necessary chemicals.
- If the pH or total alkalinity levels are high, add a pH decreaser according to the label directions.
- If the pH or total alkalinity levels are low, add the necessary amount of pH increaser to raise the levels and balance the water chemistry.
Keeping the pH balanced is the most important part of pool maintenance, and keeping the proper total alkalinity level helps stabilize pH. Test and adjust pH and alkalinity on a regular basis to keep pool water clear.
