CUSTOMER REVIEWS

Rated 5.0 out of 5 by 6 reviewers.
Rated 5.0 out of 5.0 by Miracle Cure for a Major Algae Bloom - when you can Vacuum to Waste. This product is a miracle cure to clean up a severe algae bloom. Is it a quick fix. In my experience it may take from 1 - 2 days for the "Crud" to settle prior to vacuuming, but once you vacuum all you see is clear water, as long as you don't try to vacuum to quickly, which unsettles the debris. If you take your time when vacuuming your pool with truly go from Icky to Blue with the vacuum. Keep in mind you might want to raise the water as high as possible prior to doing this because a lot of water carrying the green/brown yuck. November 4, 2014
Rated 5.0 out of 5.0 by This is a miracle pool cleaner I tried for two months to clear my 18,000 gal pool and no luck , going to my favorite pool place. The man there was very helpful but to no avail $600.00 later and it was getting greener and greener. Then a friend of mine who has the same size pool said he could clear up my pool in three days. Well I did not believe that it was possible even though his wife kept saying he was right. That he was her on personal pool man.LOL Well-- When he came over to my home I was at the point of filling in my pool and I TRULY love my pool. he put this stuff in my pool and says he will be back tomorrow and I'm thinking yea sure. The next day comes and I get up early to see this miracle and there is the proof everything has stettled to the bottom so when he comes in he just vacuums it out and we are almost to where I can jump in my pool. This man and your hth green to blue saved my pool and my happiness. Can not thank you and him enough. August 20, 2013
Rated 5.0 out of 5.0 by A Lifesaver This is a wonderful product. It truly saved our summer. Compared to the money I spent on other chemicals from pool stores, this is a real bargain. September 4, 2014
Rated 5.0 out of 5.0 by It really works! Our pool was nasty and green we were thinking of emptying the whole thing but I went to home depot and saw this and decided to give it a try. I followed instructions and our pool now is crystal clear :) June 30, 2013
Rated 5.0 out of 5.0 by Love This Product - It Works Fast! I purchased this product 7/13/12 and within 4 hours I noticed improvement. Overnight the product did exactly what it says it does. All of the dirt and algae in the water sunk to the bottom of the pool, and all I had to do is vacuum. The pool was clear and sparkly. Very good price. Easy instructions. Great results. Makes me think about letting my pool guy go. July 14, 2012
Rated 5.0 out of 5.0 by Glad you had it in stock! Since this is the end of the summer, I'm glad you had the pool supplies in stock I needed to get mine winterized until next season. October 2, 2012
