4 Causes of Foamy Hot Tub Water

If your hot tub water looks like you just poured in a big bottle of bubble bath, it’s not a good sign. As a hot tub owner, you probably know that adding soap and suds can cause a foam problem and is hard on your spa equipment. So it’s doubtful you’ve added any of these taboos to your spa.

Unfortunately, foam in your hot tub water can result from several other causes.  The most probable causes of your foamy hot tub water are:

Low alkalinity
Soft water
Dirty filters
Detergents from swimsuits, hair products, and filter cleaners

Understanding each of these reasons and the solutions to each can help you resolve your current foamy hot tub water problem and prevent it from reoccurring.
