FROGSerene Floating System for Hot Tubs - Quick & Easy Prefilled Hot Tub Sanitizer - Hot Tub Maintenance System with Sanitizing Minerals & Bromine

Very easy to use and works great! No chlorine or related issues for our hot tub.

We reuse this for many months. Works great.

I have a hot tub and these are my "go to" chemicals to keep the water in great shape. Super easy to use!

I will say that I ended up going a different route with the new Thermacore hot tub we purchased after getting the Frog Spa system! I am very happy with the customer service in resolving our situation, as we sold our SaluSpa Heliski inflatable hot tub we had before getting the SaluSpa Paris Thermacore Hot Tub!For our new hot tub I decided to go a more natural path route, without chemicals! I was definitely struggling to get the water balanced so the Spa Frog would work for us! The calcium hardness ended up reading low on the tester strip & the bromine never registered on it, even when adjusted to the highest level after several days. I never did fully resolve the issue before selling the SaluSpa Heliski that we used it in!This product is not eligible for returns, however Amazon fully refunded the money! I’m very pleased with the overall experience & idea of using less chemicals with this system than some other systems use! It was a growing & learning curve that led me to finding more natural ways of providing my family with the healthiest possible approaches to creating healing waters to soak in at home!

glad I switched to bromine; good product; fast delivery

we love the spa frog line, always works as it should. easy to use but a little pricey.

Use in spa and I’m very satisfied. Just click dial to appropriate setting using guide and throw it in.

Quick shipping and exactly what was ordered.
