What Causes Cloudy Pool Water?

Cloudy pool water is caused by the presence of particles that are too small to be filtered and are also unremovable by oxidation. There are four main reasons that a swimming pool can get cloudy water.

  • Your pool filter is dirty. In many instances, cleaning or backwashing your filter can alleviate the cloudiness issue.
  • Your pump may need to run longer. Not running your pump long enough means only a small percentage of the water is actually being filtered. 
  • Your pool water chemistry is not balanced. High chlorine is one of the top reasons that pool owners experience cloudy water, but high pH, high total alkalinity, high calcium hardness or a high TDS (total dissolved solids) can also lead to cloudy water.
  • There are environmental factors at play. Anything from weather, wildlife or even nearby construction can cause your pool to be cloudy. Environmental factors also include swimmers who can introduce things like make-up, hair & skin products or sweat into your pool.

How Do I Get Rid of Cloudy Water?

Ultimate Water Clarifier has been proven to be a superior clarifier in swimming pools and spas. Not only does it clarify the water, it also helps to prevent stains, eliminates oil and improves filter efficiency. If your pool is cloudy, follow the instructions below and you will be on your way to clear water that is safe to swim in once again.

  1. Clean or backwash your filter if applying the initial dose.
  2. Dilute 2 oz. per 5,000 gallons of pool water.
  3. Pour around the edge of the pool.
  4. Run your circulation system continuously for 6 hours and clean your filter as needed.

For severe cases, you may need to increase the dosage or simply contact your local Pinch A Penny store for expert advice.

Please read all bottles and observe all warnings and printed precautions.

Also remember, following the ABCs of Pool Care is the best defense against pool water problems. Suncoast Complete Multi-Purpose Tablets and Suncoast All In One Algaecide contain water clarifying properties, which help to keep your pool crystal clear all season long.
