Customers praise this refill cartridge kit as "easy to use" and effective for maintaining spa water clarity. Most reviews highlight the convenience of the system - "just pop them in" and water stays clean with minimal effort. While shoppers appreciate how it "takes the guesswork out," some note it's "a little spendy" at $25-30/month. A few customers mention needing close monitoring and one reported metering issues.

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!

Makes it pretty easy to cotrol the chemical levels.

Makes it pretty easy to keep your chemicals on track. Just put them in the float and keep an eye on your readings.

While a little spendy, it will last for my spa

While a little spendy, it will last for my spa for a reasonable amount of time, like $25 to $30 Ish $ per month Product works very well, consistently.

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.

Hope they keep making it.

We hope that Spafrog keeps making their cartridges. We love our 17 year old Marquee Destiny Spa. Such an easy way to maintain the water quality.

I think the quality of these cartridges has dropped

The 0-6 metering hasn't worked on the last 2 cartridges. They are like they only are on 6. I have been pulling them out to lower the chlorine level. I used to turn it to 0 or 1 to lower chlorine level.
