Green to Blue Advanced

Works amazing! I had almost given up on our algae situation and I am so glad I found this. Easy to use (just dump in the skimmer), dissolved quickly, super reasonably priced, and overnight all algae was dead and on the bottom of the pool ready to be vacuumed out. If you have algae, get this stuff!

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!!!

This product works! Will save you money and extra work! Does what it promotes! Dissolves. Algae collection is easily removed .

My pool was split pea green. I was beyond myself on how to get it clear. I bought this with hopes it would work and my pool is now crystal clear. The only reason I did not give it 5 stars is because I have an above ground pool and I don’t own a vacuum that vacuums to waste so it was a bit time consuming to siphon all the dead algae that had settled on the bottom. But it definitely worked for me and if I need it again I will definitely be purchasing it again

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!

This product is all you need to maintain a clean pool…we went away for a week and pool turned green…in 12 hours, pool returned to be crystal clear. Sharing a before after photo for proof. The photo after treatments before I vacuumed the dead algae out.

Our 25,000 gallon pool started growing algae on the pool walls. I wanted to take quick action as all the grandkids were coming over next week. I evenly applied the 4 packets of "Advanced 1" across the pool, and worked the bottom to ensure all material was dissolved (took about an hour). Then I turned on the recirculation pump and slowly poured the "Advanced 2" packet into the pool skipper as directed. Within 15 minuted the pool pump slowed to 20% due to my 4 large filters being terribly clogged. RESET 1...I stopped the pump, removed the full set of filters, and cleaned each of them with a water jet spray, resealed the filters into their pressure container and reset the pump. RESET 2....Pump pressure and water flow was normal for 30 minutes, then degraded within the hour. I stopped the pump again, removed the full set of filters, and cleaned each of them again. RESET 3....Pump pressure and water flow was normal for first hour, then degraded in 2 hours. yep, had to start all over cleaning out the filters. By now it is getting dark and had to stop for the day DAY 2.....Pool water is still super-cloudy and cannot see bottom drain. Restarted pool pump. It lasted about 2 hours this morning and again clogged. I am hesitant to put in 4 new filters for fear of ruining them as well. So still using my 1-year old filters in hopes of clearing out most of the micro-particulate materials suspended in the water first. Then I will replace filters. I see no improvement in the super-cloudy particulate water but will continue the process. THIS WAS NOT THE PLAN. I only hope I can get the water clear enough for the grandkids this week. The amount of time spent so far is just crazy, and no remedy in sight yet. Some customers are happy, but I will forever AVOID THIS PRODUCT and MANUFACTURER.
