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

If you don't have this product run and grab it. The compatibility was great no harm hot tub stays clear. Instructions were great on how to handle and how to use it. Everything was packaged gray nothing was broken it's very durable and lightweight.

This takes the guess work out of maintaining a hot tub. Makes it super easy. Just read the instructions and you'll be set. I've been using this consistently for 2 years and I've yet to run into any issues. Keeps the water balanced, water smells good. No harsh chlorine smells.

The FROG Serene Floating System has made hot tub maintenance so much easier. The quality of the system is excellent, and everything feels durable and well-made. I was pleasantly surprised by the smell, there is little to no chemical smell compared to other chemicals that we have used on our hot tub. The components are very easy to set up and very easy to replace. I appreciate the longevity of the cartridges, which last a long time and reduce how often I need to check and adjust the water. The water stays crystal clear and the overall clarity is impressive. Our hot tub feels cleaner. softer and more enjoyable to use. If you want a convenient and reliable way to maintain your hot tub, this system is definitely worth it.

I have been using the Frog brand for my pool needs for years so I was excited to try the hot tub float device and I am impressed with how easy it is to use and the results are great. We just filled our hot tub for the season and since we live in the countryside, there can be alot of pollen that can quickly change the balance in the water, so I like thay this maintains the water and includes test strips so that I have some guidance in what my hot tub needs. They also included some extra shock treatments but I havent had to use those yet because this has kept the water perfect. I would recommend to anyone.

I do not like how quickly it dissolves and I do not like how I not recommended how to use it because you don't leave it in while you are in the hot tub because that sounds stupid haven't floating around while you're in the hot tub so do I put it back in but there's no instructions so I think it's stupid and that's why I gave it three stars because it works but doesn't work while I'm in the hot tub... duh stupid as crap

It truly delivers on a set and forget workflow for weeks at a time. Instead of daily maintenence, your main job is checking the water once or twice a week with test strips and tossing in non chlorine shock after heavy use or on a weekly schedule.

I was pleasantly surprised by the fact that this product had very low odor. It works well and will definitely help keep me up with my maintenance. The components are sturdy and not cheaply made.

The effectiveness & how in handy this has been already is incredible you can just spot the difference in using it for a few days the color change in the water!

This was installed very easily. It has been too soon to notice a different but very easy to manage. Packaged very well. Recommended to my sister who also has a hot tub

This system is super easy to install and maintain. It is gentler than chlorine too. I really like how easy it is to maintain my hot tub now compared to before
