## Customer Reviews

### ⭐⭐⭐⭐⭐ Awesome Product
*by N***O on June 4, 2024*

I never write a review, but I have to say this product really worked on our poolsWe have a copper/silver filtration system and at our pool opening the level was left too high. We come out one morning to find our pool with huge brown spots on the bottom and lots about 4ins of metal stains on the side of the pool.We knew we had to get the cooper levels lower so we did a metal out treatment, but with the levels still a bit high we were looking for something to remove the side staining. And have to say using the product really did work. We still have a bit of staining on the sides, but hoping that with maybe another few days of this product running thru will clear that up too.

### ⭐ Did not meet expectations
*by W***. on May 15, 2025*

Followed all directions. I am not surprised that the product did not help at all in removing blue green copper stains on the plaster since the stains had been there several years. I was very disappointed though that it had no effect on a handful of recently formed quarter sized rusty colored spots on the plaster. It also caused a yellow green color in some places on the existing blue green stains and they look worse than before.

### ⭐⭐⭐⭐⭐ Works great.
*by T***S on September 7, 2024*

Scrubbing or brushing pool is not necessary. Slowly pour half a bottle around pool and give an hour with pool pump running and pool is spotless.
