Green to Blue Advanced

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 really works!! It's a little time consuming but well worth it! Not a lot to do, just have to wait for it to work. We use it to open our pool every year.

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!!!

Don't waste your money going to the pool store first like I did! Purchase this first to take your pool from green to blue over night! I can't recommend this product enough!

The best stuff to tackle that algae problem. Follow instructions and your pool will be blue the very next day.

Can't say anything particularly good or bad about it. It's thoroughly average in every way. Nothing remarkable. From my perspective.

Works as advertised. Fantastic product. Follow the directions closely. Because the size of the pool determines how much chemicals you need. I will definitely purchase this product again.

I have a 14' vinyl pool. This stuff did kill the algae, and the water did clear. The problem is all of the dead algae sinks to the bottom of the pool. A small pool vacuum will do nothing but stir it back up and cloud the water with brown muck. I tried a different vacuum with the same result. I tried using the filter, but the filter clogged in less than an hour. After 3 replacement catridges, I ended up having to drain my pool to get as much of the muck out from the bottom as possible, which meant brushing it back up after it settled about ever 30 minutes. I am hoping I got enough if it up for the filter to take care of the rest. I will never buy this stuff again.
