Have you ever noticed that your hot tub seems full of foamy water? At SpaMate, we know that this is a common concern for many of our customers. So, what causes hot tub foam and how can you get rid of it? Let’s take a look.

Causes of Hot Tub Foam

There are a few different causes of hot tub foam. One of the most common causes of hot tub foam is soap and body product residues. Without realizing it, many homeowners hop into their hot tubs with makeup, perfume, hair products, soap, and body lotion still on their skin. These products, as well as fabric softener and skin oils, can quickly cause hot tub foam to build up in your spa.

Low calcium hardness could also be the cause of this foam. Low levels of calcium in your hot tub decrease the surface tension in the water, which allows for the foam to form.

Imbalanced pH levels can cause a variety of issues in your spa. One of these problems is hot tub foam. Other issues that can be caused by pH imbalances include green water and a stench coming from your spa.

Getting Rid of Hot Tub Foam

If the cause of your hot tub’s foam problem is likely from beauty and similar products, you can try using a scum digester. You can also use an oxidizing shock after each time you take a dip in the hot tub. A floating oil absorber can also help. To prevent this foam buildup in the first place, you can quit using fabric softener on your swimsuit, and you can rinse off in the shower prior to getting in the hot tub.

You can get rid of hot tub foam caused by low levels of calcium by adding a calcium hardness increaser. You should also use calcium hardness test strips at least once a week to check the level of calcium in your water, which can help you better maintain proper levels of calcium in your spa.

When imbalanced pH levels are the cause of your hot tub foam, you will need to start your fix by testing the water’s pH levels. You might need to raise low pH or drop high pH. You should be testing your levels at least once a week to ensure that your spa water is healthy.

Spa chemicals are going to be your best bet for getting rid of hot tub foam without draining and cleaning your spa. Once you get rid of hot tub foam, you can also take preventative measures to prevent the problem from occurring again. Testing your hot tub water for all the necessary chemicals and balances is a good place to start.
