What Causes Foam in a Hot Tub?

By Bullfrog Spas of OKC, September 22, 2020

The question, "Why does my spa foam?" is commonly searched online. Fortunately, it is not a severe issue for hot tubs, OKC. Once you understand what causes foaming in a hot tub, you will be able to take the necessary steps to prevent and address the issue.

Why Does a Hot Tub Get Foamy?

What causes foam in a hot tub? The simple answer is surfactants. These are molecules that combine with water and air to create surface tension. This mixture is what causes foaming in a hot tub.

To prevent hot tubs OKC from foaming, consider the common surfactant culprits. Many of them are personal hygiene products such as deodorant, lotion, shampoo, laundry detergent residue, and other chemicals that will throw off the balance of the spa's chemistry.

Surfactants also build up in hot tubs with spills from food and drinks. If you eat and drink in your spa, it could answer the question, "Why does my spa foam?" To maintain your water chemistry, consider dedicating your hot tub to relaxation only.

Addressing Foam

Now that you know the answer to "Why does a hot tub get foamy?" you can address the issue when it occurs.

● Start by testing your water - Focus on pH, sanitizer levels, alkalinity, and TDS (total dissolved solids). These should help you pinpoint problems.

● Check your calcium - Low calcium levels means that the water is soft and more likely to foam. Without enough calcium in the water, there is a risk of damage to the hot tub. Make sure to test the water hardness weekly.

● Drain and refill - If you have foamy water, the best course of action is to drain the hot tub's water. Be sure to turn off the power, and follow the instructions to drain your spa. It may also be necessary to change the filters, so look at them carefully. Clean out your hot tub before refilling it.

● Chemicals- Once you have refilled the tub, make sure that you replace the chemicals to keep your water safe and clean.
