You come home from a long day at work and you can’t wait to enjoy a dip in your hot tub. But what if your spa is covered in a layer of foam?
Unfortunately, that evening soak is out—at least for now. Cloudy or foamy water is often an indication that the chemical balance of your spa water is not quite right. Over time, this can even cause damage to your hot tub, corroding certain parts or discoloring the walls. But don’t stress. Once you understand where cloudy and foamy water comes from, you can get rid of it quickly and take steps to maintain crystal clear spa water in the future.
Cloudy and Foamy Water Caused by Bathers
Cloudy and foamy water is sometimes caused by soap, shampoo, and lotions that slough off people’s skin or bathing suits as they soak in your spa. To rid your water of these unwelcome guests, shock your spa after every big party, and routinely at least once a week.
When Mother Nature Wants a Dip In Your Spa
Hot tub foam may also be caused by leaves and other debris decomposing in your hot tub. Your sanitizer is designed to rid your spa of bacteria and algae. But if you aren’t manually removing leaves and grass, the sanitizer can’t do its job to kill bacteria and algae. The unfortunate result? Cloudy water or hot tub foam.
A Bad Chemical Balance Can Cause Hot Tub Foam
Cloudy and foamy water may also indicate that your hot tub pH balance is off. You can add the right mix of hot tub chemicals to correct the problem. First, test the hot tub water with a chemical kit. Water with a pH greater than 7.8 parts per million has too much pH, while hot tub water with alkalinity higher than 120 pm is too alkaline. Either problem can lead to cloudiness.
