Frequently Asked Questions

Algae in a hot tub can take many forms and appear in various colors. Your spa water could appear greenish or cloudy, or the sides of your hot tub shell could feel slippery and slimy to the touch. Algae will form in a hot tub when the pH levels in the water are imbalanced or the sanitizer levels are not kept at the proper levels (between 3 ppm and 5 ppm). Sunlight makes algae flourish, so don't leave your hot tub uncovered for extended periods of time. You can prevent visible algae or hot tub slime by using Spa Selections Algaecide. For an indoor or outdoor spa, use Spa Selections Algaecide on a weekly basis to eliminate algae in your spa.
Spa Selections has a two-part bromine system that includes Spa Selections Bromine 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 and doesn't irritate your eyes or bleach bathing suits. Additionally, bromine is still 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 bathers 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.
