Hot Tub & Jetted Bath Secret™ is a unique, environmentally friendly dual purpose additive that greatly improves water clarity for Hot Tubs and "purges" bio-waste from Jetted Bath Tubs. This amazing gel will keep Hot Tub water crystal clear and will remove any build-up of gunk, hair, oil, lotions, cosmetics, dead skin and other contaminants from the plumbing, jets, and shell of typical jetted bathtubs. This gel works quickly, efficiently to make your bathing experience super healthy. We GUARANTEE you will love Hot Tub Secret™. Less than 1 teaspoon of the Hot Tub Secret™ Gel per week will keep water clean and clear, fresh smelling and non-irritating for most average sized Hot Tubs under 500 gallons. We recommend small amounts of a sanitizer on a daily or weekly basis, since Hot Tub Secret™ is not a sanitizer. Sanitizers kill bacteria and other disease carrying organisms that can harbor in frequented Hot Tubs. That's it! For less than $60 per year, you can enjoy the clearest Hot Tub water you've ever soaked in.
