Why Does Your Hot Tub Foam and How to Fix It

Have you ever wondered why your hot tub foams? Does the foam ever make you question how clean your hot tub or your body is after a swim? Foams are great if you’re taking a nice bubble bath, but if you’re just looking to relax in your hot tub with clear, pristine water, foaming is not what you’re looking for. Excessive foam is not a serious issue, but it is a common problem faced by hot tub owners. Here are some tips to help you understand and pinpoint the cause of your hot tub foam and some simple ways to fix it.

Lots of variables cause foaming in a hot tub. The beauty products you use such as body lotion, hair products, and makeup can all cause waters to be foamy. When body oils and cosmetic residues on your skin meet with the natural alkalinity of the water, “soaps” form and create foam. The simplest solution would be to take a shower and remove all your makeup before you step into the hot tub. But if that’s not possible, or if you just prefer going to the hot tub all pampered up, scum digesters can clear the water from soap residues and beauty products.

Now that you’ve gotten rid of the foam, try to follow these steps to prevent foam from forming in the future. Always use the right chemicals at the recommended amount. Not only will a balanced chemical level eliminate foam, it will also ensure safer waters for you to soak in. You should also clean your tub regularly to eliminate possibility of residues. If you prefer going inside your hot tub in a bathing suit, make sure to rinse it off with fresh water first, as soap residues will cause foam to form.

If you’ve already followed these simple tips, but there is still foam in your hot tub, perhaps there is a chemical imbalance. Test your hot tub water with test strips that will determine the alkalinity, pH, and chlorine/bromine levels. Adjust the high pH levels with a pH decreaser to prevent foam from forming; however, having a pH level that is too low is also dangerous. So, it is suggested to test your water every week to maintain a healthy balance. An alternative would be liquid testing, which only checks pH and chlorine, and tells you if you have too many or too little chemicals in your hot tub. Low calcium levels also cause excessive sudsing. Just like the pH levels, use the calcium hardness test strips weekly to keep the calcium hardness level balanced as well.
