There’s nothing like a crystal clear pool. It’s the standard of pool ownership. However, for various reasons, pool water can become cloudy, ruining the beauty of your pool. When cloudiness occurs in your pool, it’s important to consider the factors that are causing it.First, let’s take a look at your water’s chemical balance. If your water is not balanced properly, this could lead to cloudy water. If your pH is higher than it should be, above 7.8, it could cause minerals in the water, like calcium, to come out of suspension and cloud the water. Another factor to consider when dealing with cloudy pool water is your chlorine level. Cloudy water is usually the first sign that a bigger problem may be on the horizon. If your chlorine drops lower than 3.0 ppm for any given period of time, your pool is susceptible to bacteria or algae growths that can begin with cloudy water. This is most common after the pool has had several days of heavy use. If water balance is the culprit, immediately adjust your pH or chlorine levels. Lowering your pH to the appropriate 7.2-7.8 should clear up your pool water. If it’s the chlorine level that is causing the cloudy water, shock the pool immediately, and make sure you have a steady supply of large chlorine tabs feeding the pool to maintain your chlorine level above 3.0 ppm.
