  • Hot Tub Foam? Get Rid Of It

  • Do you ever open your spa cover and find the tub full of foamy water? This is a common hot tub problem and leaves many people wondering, what causes hot tub foam?

    Below, I’ll explain the causes of hot tub foam and how to easily fix this problem for good!

    There are three main causes of hot tub foam:

    1. Beauty Products

    Believe it or not, foamy water can be caused by soap residue in your swim suit, as well as fabric softener, body lotion, hair products, skin oil and makeup.

    Using a scum digester, such as Scum Buster will remedy foamy water caused by soap residues and beauty products. You can also help prevent hot tub foam by using your oxidizing shock after each use and a floating oil absorber, such as a Zorbo.

    2. Low Calcium Hardness

    Low calcium levels (aside from being damaging to equipment) can also decrease the surface tension in the water and allow for excessive sudsing.

    To prevent this issue, use Hardness test strips once a week to check and maintain the calcium hardness level in your hot tub.  If low, use Calcium Hardness Increaser.

    3. High or Low pH

    Imbalanced water can cause all sorts of issues, from green, to stinky, to even foamy hot tub water.

    Prevent foam due to high pH by using pH Decreaser. Use Easy pH for raising low pH. Test your water once per week (once every two weeks if using CWB) to maintain a healthy hot tub.

    Based on the cause of your hot tub foam, here are some helpful products:

    · Oxidizing Shock
