Spa Chlorine & Hot Tub Sanitizers
Maintaining a clean, bacteria-free hot tub is essential for your health and peace of mind. High-performance spa sanitizers eliminate harmful waterborne contaminants—including algae, bacteria, and organic buildup—that thrive in warm water.
By making quality sanitizers a core part of your hot tub maintenance routine, you ensure your spa water stays crystal clear, balanced, and safe for every soak.
Spa & Hot Tub Balancers
When your pH rises above 7.8, Spa Down quickly lowers total pH levels to maximize sanitizer effectiveness and prevent water discoloration.
If your pH drops too low, Spa Up raises pH levels above 7.2 to protect crucial hot tub equipment from corrosion and keep your sanitizer working efficiently.
For long-term stability, pH Balance+ locks in target pH levels to protect against equipment damage, clarify cloudy water, and eliminate skin and eye irritation.
If you live in a soft water area, Calcium Booster raises calcium hardness levels to stop surface corrosion and prevent unsightly hot tub foam.
