Hi guys, I'm new to the forums but I decided to join for a simple question which is really bothering me. I had an algae bloom just last weekend since I was gone for a while and came back to find the pool green. I fixed it all an now all I have left is the dead algae at the bottom. I tried vacuuming but I guess that cartridge filter doesn't filter it because the water coming from the return jet became green after a few minutes. I bought a backwash/discharge pipe today but sadly I don't know how to use it. It came rolled up and when fully extended its about 50' but it's flat and I don't know how to inflate it. Could someone please direct me into how inflate it so I could use it. Also it came with a little clamp which I'm guessing is used to hold it to the waste valve of my filter.
