Love it!

We love this system. It has saved us $$ on chemicals.

Good product

I have been using the Spa Frog Bromine cartridge for 10 years. It has been a consistently good product and has kept my hot tub in chemical balance. I highly recommend the product. The price has risen dramatically, but name something that hasn't.

All is good.

The Frog System is Great

I have been using the floating Frog Mineral & Bromine Cartridges for years. They are easy to use and help build confidence in a clean and healthy hot tub. Spa Depot is a dependable web store for all my hot tub needs!

spa frog

item is simple and easy. I've had it in use for about 4 months and it seems to reduce constant addition of granular but I really cannot see much of a difference other than I feel like I can go a couple days without checking the levels with some confidence.
