Stain and Scale Control for Pools, Spas and Hot Tubs

I am using this in my hot tub. I ran out of the old stuff a couple of week before this came. I was seeing some build up on the rim of my hot tub so I put in the recommended dose. ( I don't recall what that was right now - I think one or two ounces. I ran my pumps on high a few times all the buildup was gone. This is probably a 2 year supply for me. Money well spent.

On my auto ship list.I have bought this scale remover since owning my spa.This weekly along with spa shock and clarifier and I don’t even have to test anymore.Spa water spays crystal clear and no grim build up!!!!

Does what I need it too.

Does what its supposed to do.

This really helped our pool. Will definitely buy again!!

Great price for a good product that does the exact same as its more expensive counterparts. Will purchase again!

I have a problem pool for the moment and will soon have it treated for black algae but this product is mostly for scale and I think it works ok. I also use it in my spa hot tub.

I use this in all my indoor and outdoor fountains. Keeps the water clean up to 1 month. Saves me time, don't have to clean as often
