Stain & Scale Control, Metal & Mineral Remover for Hot Tubs, Spas & Pools, Prevents Scale Buildup, Protects Plumbing & Heater, Works with All Sanitizers, 32 Ounce

We were having a problem with “tea” colored water after only a day and this cleared it right up. The bottle is marked to make it easy to apply specific dosages and we are testing with small amounts to start.

Good product

Easy to open easy to use

I had a large amount of friends and family in my hot tub recently, which left it very cloudy. I used my normal cleaning chemicals in hopes to clear things up relatively quick and without throwing off my hot tub's chemistry. After purchasing and adding this product my hot tub was completely clear within a day or so. In addition to adding this product I also cleaned the filter and increased the run cycle. I have no doubt that this product was the saving grace for me spending more time and money. I also appreciate how relatively inexpensive this product is considering it has 32oz.

No comments, see title.

Made a big difference in the feel of the water and I no longer get a weird whitish ring in my hot tub. Our water here in Texas isn’t what I’d call pristine, but this stuff does a great job of eliminating all of the scaly whitish grit that usually builds up around the waterline And it gets the green tinge out of my water. I highly recommend it.

This is our second time of purchase, we get two hot tub fill out of this size bottle for a fraction of the price of the others. We use well water to fill our hot tub, which is set up for outdoor use only, you can only imagine how much stuff come out in the spring having not been used for 5 to 6 months, even letting it run for awhile we add a sock to the end of the hose and put this stain and scale in at the fill, wonderful job. Second fill of the year we don't need the sock, just stain and scale. Great product, great price.

A spa technician recommended this product. The water chemistry has changed frequently , and the spa was getting a lot of particles in it. I put more preventer in, but it wasn't working. This really helps to eliminate the mess,
