If there is debris in the pool which is causing the water to become dirty, it would be a good idea to clean out the pool before swimming. If the water has too many chemicals, it would probably best to stay out of the pool until the chemical levels are balanced out.

Why Is My Swimming Pool Cloudy?

There are a few different reasons why your swimming pool may be cloudy. These reasons are:

  • Imbalance of chemicals: The chemical composition of a swimming pool is what makes it safe and clean to swim in. Having an imbalance of chemicals can cause your water to become cloudy. This can indicate that there is too much or too little chlorine, an off pH level, alkalinity, calcium hardiness or stabilizer. Most pool equipment stores will test your pool water sample for you which will help you decide which chemicals or levels need to be balanced.
  • Faulty filter: A pool filter should run very often, however, if the water becomes cloudy and appears to not be clean, it could be the filter. It is important to maintain your pool filter. Replace or clean out the filters and maintain upkeep to ensure that it’s working properly.
  • Environmental factors: Sometimes, environmental factors impact the pool water. Debris from wind or storms can fall in the pool and runoff rainwater can make the pool appear dirty or cloudy.

What Chemical Imbalance Can Cause My Pool To Be Cloudy?

The chemistry of your pool is dependent on the proper mixture of chemicals. If these pool chemicals are off-balance, it can impact the quality of your pool water. If your water is cloudy, it may be because the pool chemicals are off. These chemical imbalances are:

  • Improper pH and chlorine levels: The pH level and chlorine level are the #1 reason behind most cloudy water situations. While the pH is not directly responsible for the cloudiness of the water, it does impact how the other chemicals of the pool react which can cause cloudiness. If the pH is too high, it will cause the calcium to not dissolve properly and calcium scaling. If the pH low, the chlorine will become reactive which forms combined chlorine and can cause cloudy water.
  • High total alkalinity: You should keep track of the alkalinity level in your pool. A high level can cause an imbalanced pH and calcium scaling which can cause a cloudy pool.
  • High Calcium Hardiness: If the calcium levels in your pool are too high, it will lead to excess calcium which can cause a pool to be cloudy. This can also cause a filter to become clogged with calcium deposits.

What Do I Do If My Pool Water Is Cloudy?

Depending on the reason behind the cloudiness, there are several things that you can do to fix it. First, you should either use an at-home test kit or provide a sample to your nearest pool store which will tell you why the water is cloudy.  Make sure you understand the basics of pool care for keeping your pool water clear.

If there is an imbalance of chemicals, you must follow the recommendations of the pool store and attempt to balance out the water before it gets worse. Unfortunately, the only fix for high calcium hardiness is to drain your pool.
