I am so happy that my pool looks like this when I took the cover off today. And this is how clear it is all year long! If there is anyone who is visiting this sight and is wondering if this system works, I can say it does and then some! Two years ago I was a first time pool owner and didn't know anything. Now my pool stays crystal clear all year long with no strong chemical smell. I just gave a donation to this sight as I feel it is so wonderful and I have told so many about it. Thank you, thank you, thank you!
