This product is simple to use and works well. It was priced better when it was part of a kit. Used in conjuction with other products in the line, it provides good tub chemistry.

This system works very well, and I always use it at startup of fresh water in my hot tub.

The Cleanwater products are great, We have been using them for several years now. Soon after we purchased a new hot tub my wife developed a severe allergic reaction to the usual chemicals that are used in hot tub treatment. At the time we thought we would just have to do away with our hot tub. Lucky for us we found the cleanwater products on the SpaDepot website. They work great & we couldn't be happier.

I really like the mineral system vs bromine or chlorine. Would buy again.

Can't say how good the prep works as I haven't run hot tub without it. The Cleanwater Blue system is easy to use, works great and fairly inexpensive over time. I wouldn't use anything else.

Works great for startup

I've been using the Cleanwater Blue chemicals for several years in my spa and it works great and I only need to test chemicals twice per month. Also when I drain the spa it doesn't harm plants.

good price fast delivery

A little complicated to get started but once everything is in and balanced very easy to maintain. Water stays crystal clear and stays that way for quite a while. Follow the directions

Have to use every two weeks or more to completely get rid of the calcification.
