Eliminate foam from your hot tub...

This is a list of some of the common causes of foam in your hot tub. Excessive foam in hot tubs is a common problem for spa owners but while foam will not harm your spa it can spoil the pleasure. Here are some common causes and cures.

Chemicals - Cheap chemicals contain fillers which reduce the effectiveness of the chemicals and so increase the foaming. Adding too many chemicals can also cause more foaming. Consider purchasing quality chemicals and only applying the recommended amounts.
Total Dissolved Solids - Every time you add chemicals to the water the amount of dissolved solids increases therby increasing the foam. Ensure you clean your filter/s in accordance with our Spa Filter Care section and replace the filters in-line with the results from taking our Estimated Filter Life Test. Always use a range of quality chemicals designed for hot tubs such as those found in our Spa Chemical section & consider changing your water on a 'change a 1/3rd a month basis'. As the name suggests, remove a third of your hot tubs water and replace it with fresh water each month - use one of our Pre-filters when adding water to your tub.
Body Products - Any residue from shampoos, sprays, gels, lotions etc. will cause foaming. To avoid this get into the habit of showering with just water before using your spa. If you have long hair you can avoid maximum contact with the water by either tying your hair up or wearing a cap.
Bathing Suits - If you wash your bathing suits with detergent your washing machine will never remove all the soap during the rinse cycle. Consider washing your bathing suit more regularly without added detergent.
Food & Drink - Probably an obvious one, but spilling anything into the tub will contaminate the water and add to the foaming.
