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

Worked perfect and shipped quickly. Saved me a trip to town.

I can always stress the frog to provide a clean chlorine, free, smell free, hot tub that my entire family can enjoy gets the water clear. It’s easy to open as easy to follow the directions.

We have used it for years with our hot tub. The jumpstart packet is great after cleaning and refilling. We then put the system in the next day. Heck of a lot cheaper buying it on here than through one of our local pool stores.

my tub came with an in-line chemical system but the plastic holder for the silver and bromine cartridges disintegrated over the course of ten years. This floater is an excellent replacement.

I had been managing my hot tub myself checking all of the chemical weights. After draining my hot tub I decided to try a different approach. I placed this in and did not have any issues. We have continued to use it since while replacing the yellow one. My husband seems to like this better than the other method of balancing all of the chemicals. New filter, new water, new chemical method. No issues since. The smell is normal. Chemical smells of pool products. As far as cost, I think the longevity of the minerals makes it worth it. The bromine went a little faster than I expected. Time is money and the product seems worth it when I have a working hot tub now with less thought required.

It was great for the first month, then I had to keep adjusting the bromine cartridge, then the water turned cloudy and I realized that the bromine cartridge was empty! It is hard to tell. So then I had to quickly get my old system going with the few chemicals I had left for it, and shock the cloudy water, now I have two things floating in my hot tub! I hate that I have to buy more of these just to use this system - way too wasteful! I try very hard to NOT buy single use plastic containers, so I will be looking for a different solution.

These cartridges were so easy to use. We have a hot tub in our outdoor backyard and we literally just pop them in our hot tub and we are good to go love how they were delivered on time. We are hooked on this one.

I'd been having hella problems with my Frog canister chlorine dispensers. it seemed like no matter how low set, the chlorine would be gone in a matter of days, and the water would go cloudy instantly. I decided to try the switch to bromine and it's been a huge improvement. The bromine cartridge lasts as long as it's supposed to, and can be refilled with inexpensive pellets if you don't want the expense of buying disposable cartridges.
