PoolRx Mineral System: Spas 100-400 Gallons

There is always a little doubt when trying a new product, especially when it will take a while to determine how well it works. I've used this product now for over a year (replacing as instructed). It's worked fine, is easy to use and a savings over competitive products. I'm pleased and plan to continue using it.

Great product

I liked the old ones better. They fit in my filter basket. Now it just floats around in the way. But I guess it does the same job...

I use this product in my skimmer.

I use this in my hottub. Minimal use of chlorine, so no skin irritation. Water stays clear. excellent product.
