Best decision we've made about hot tub maintenance. It has saved us so much hassle and has lasted over a month for the first yellow cartridge. The water looks clear, clean, and smells good. Very happy I stumbled across this product.

First time using a bromide sanitizer for my spa . This product was recommended by my knowledgeable salesperson. It has both mineral and bromide for clear water quality, no smell like chlorine sanitizers . Bromide works best in hot water spas and dose not break down as fast chlorine. Keeps my spa levels in the right area for use .

My skin had become highly sensitive to chlorine, and it was really affecting how much I could enjoy my hot tub. Since switching to bromine with this system, it’s been a total game-changer. My skin no longer gets irritated, and I genuinely love and look forward to using my hot tub every day again. The combination of bromine and minerals keeps the water clean, balanced, and gentle—plus, it’s so easy to use. Couldn’t be happier!

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!
