Keeps my spa nice and clear...
Keeps my chemicals at the right level with very little effort from me.
They do the job in our older hot tub….
Use with Frog cartridge holder. Works great!
Works well with our hot tub, only thing is making the plastic around it easier to remove.
They say it lasts a month, it only lasts 2 weeks...the frog system is costing over $50..just the frog system...
We use both the mineral and the yellow Frog cartridges together in a Frog holder in our spa. ..continuously. So much easier and better than balancing chemicals everyday!
things are a little expensive
Have used these products for 5 years for our hot tub. For me, it is excellent.
These mineral cartridges are used in my hot tub. These are the same brand that was installed in the tub when it was delivered. I expect that they will perform exactly like the original cartridge, but at a lower cost to me.
