I forgot to mention that there are several videos on youtube. Start with this one: or use their search bar to look for the green pool or algae or clean pool filter, etc....

If you haven't changed out your filters, that may be a start. I had that problem and decided to drain my pool. Then I performed and acid wash. After that I painted it and filled it up again. The algae came back, so I cleaned out my sand filter (which was totally green with algae). I have since used a yellow out product from WalMart and some chlorine. There is also some "anti" algae liquid you can buy at Walmart. So, try to change out sand first, then add the algae killer with chlorine. That would be easier than going thru all the stuff I did.

Can anyone tell me why the pool water level drops when I set my vari-flow valve to filter and it sends the water out to my drain? I have to keep a hose running into my pool because if not the level drops so low that the skimmer can't function. A pool guy told me I needed to change out my sand filter, which i have done, and it continues to do it. I want the water to be filtered by my sand filter, but instead it goes down my sewer drain. Any help is appreciated!
