4 Causes of Foamy Hot Tub Water

Some spa owners seem to constantly deal with foamy hot tub water so how can you correct and prevent foam from occurring in your hot tub. The key is to understand what causes it.

Four major contributors are the difference between struggling with foamy hot tub water and stopping it from starting in the first place. Detergents that have been introduced to the water are the most common cause of foaming. Residual soap, shampoo, creams, lotions, hair products and laundry detergent and bathing suits all contribute to detergent based foaming.

There are even some filter cleaning products that contain detergents which cause foam. To fix this, have bathers shower thoroughly before using the spa, launder bathing suits without detergent and use a no foam detergent free filter cleaning agent like Spa Marvel Filter Cleaner that will not cause foaming.

Dirty or improperly cleaned filters are another culprit. Filters absorb lotions, creams and oils and if not properly cleaned can contribute to persistent foaming. To correct this install a new or properly cleaned filter and shock the water.

For detailed instructions how to clean your hot tub filters you can view our video of filter cleaning or email us for detailed instructions at solutions@spamarvel.com.

When shocking the water to help eliminate foam caused by detergents and dirty filters apply shock according to the directions on the package and then wait at least 24 hours. If foam persists rinse filters thoroughly with fresh water and repeat the process every 24 hours as necessary.

Improperly balanced water is another contributing factor. Alkalinity below 80 parts per million will cause foaming to increase your alkalinity to between 80 to 150 parts per million. Calcium hardness below 175 parts per million can also cause foam. Increasing calcium hardness to between 175 to 250 parts per million will reduce and eliminate foam.

Following these guidelines will help you get rid of and prevent foamy hot tub water from happening.
