Stain and Scale Control for Pools, Spas and Hot Tubs

Works well in my hot tub. I use it every 2 weeks.

Always use to clean the filters! Works great!

I have super hard water, seems to help some

Works to clear rusty orange from my well water for both my above ground pool and hot tub! I have already purchased another bottle! Great price compared to pool store products for the same thing.

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!!!!

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.

We have really hard well water. I purchased this for our hot tub. I feel like the Clorox brand worked better for us. This did the trick for the stain removal for a couple of days but I didn’t like the smell.
