spa chemicals

these were recommended from the people we bought the spa from and they work great and very easy to refill

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.

We have been using these for years and are very happy with the balance of our spa water.

Trusted seller

We always order from SPA DEPOT when we need supplies for our hot tub. They are fast accurate and their prices are excellent. They are fully stocked with many brands, you can’t go wrong!
