SpaPure Hardness Increaser - 1 lb

Love Spa Pure Products

I use this to increase my spa hardness level as it seems ours is always low. It does bring the level up and helps keep all my levels where they should be. I use all Spa Pure products and am very happy with crystal clear water!

Right Stuff

There isn't much to say here. We need this for our hot tub - on a steady basis, so why wouldn't we buy "in quantity"?
