Easy to use

Great product that is easy to use and takes a lot of the guess work out of keeping the spa water clean and sparkling.

Frog Sysrem cartridge

It is very easy and convenient using the frog cartridge, but very expensive wish there was a price drop!! . I really like $1 days.

Great way to take care of the hot tub!

We've been using Frogger for as long as we've had our tub, about 18 years, and it makes it really easy to control the levels.

Nervous learning about new product

This is about new product Alkalinity Up & Ph with the 5 pages of how and when to use it. It was much simpler to use these products separately.
As always love the Frog set of cartridges. Reliable over the years.
