Frequently Asked Questions

A common cause of foam in spas and hot tubs is the turbulent water combined with lotions,  soaps and detergents from bathers and their swimsuits. Showering before entering the spa and using Spa Selections Foam Out helps reduce the amount of foaming. Organic waste build-up can also cause foaming. If you are sanitizing your spa with bromine, you should shock your spa with Spa Selections Non-Chlorine Shock Oxidizer on a regular basis to oxidize the waste out of the water and reduce foaming.
Spa Selections Bromine is a two-part system, including Spa Selections Brominating Tablets and Spa Selections Brom-Start. Overall, bromine tends to be more popular among spa owners because unlike chlorine, bromine is effective over a wider pH range, doesn't irritate your eyes and will not bleach bathing suits. Additionally, bromine is an effective sanitizer in its combined form and doesn't smell.  Many spa owners, however, elect to sanitize with chlorine. Chlorine is traditionally used in pools and is an effective sanitizer and oxidizer. Spa Selections Chlorinating Granules are easy to use and keep the water sparkling clean!
How often you shock spa water depends on the sanitizer and the number of users in a 24-hour period. If you are using Spa Selections Bromine Tablets and Spa Selections Brom-Start, it is recommended that you shock each time you finish using your spa. If you are using Spa Selections Chlorinating Granules, it is recommended that you shock at least one time per week. It may be necessary to shock more often if the user load is heavy or the water is cloudy.
