Worth the money to get your pool green free
Best invention for green pools. Love how fast it works and makes the water clear. It may seem expensive, but it's strong to get that green out! I love having back up of this product in this hot weather since it plays havoc on pools,

This stuff is AMAZING!!! 🤩
I bought this on a friend’s recommendation & it worked like a miracle! My husband went through a pretty informative “pool school” when we bought our pool several years ago & has done great at keeping it clear & maintained. This past year we didn’t close down our pool properly & it was green with leaves, debris & tadpoles living in it. He shocked it several times & added chlorine & clarifiers but discovered it was too alkaline & chlorine locked. The water had cleared up somewhat & turned a slightly greenish hue, however we could not see the bottom. I ordered the Green to Blue & neither of us were too optimistic it would truly work. To our surprise the next day we woke up to crystal clear water & we could see all the way to the bottom! The powder you put in circulates & then falls to the bottom so you do have to sweep it out afterwards but your pool water will turn out beautifully blue & clear! We will definitely be buying it every year from now on!!!

Green to Blue “product name says it all”
I have used this to open my pool every year for the past several years and it works every time I’ve used it. It truly takes a green pool and turns it blue overnight. Yes you must vacuum to waste the following day but it works perfectly every time. Highly recommended

Magic product that you can count on when you have real green pool
This is the magic item that I have been using since years. When you have dark green pool, just bring your filter valve recirculating position, add 4 white powder directly in pool and 2 brown powder bags into the skimmer. Setup your times and run Pump 2 hrs. Shut off everything. Let water stay still without any movement (no brush, no skim, no adding water, no robot. 12-24 hrs layer, you will see the magic. Slowly, vacuum to waste. Done
