We have a 27' above ground pool. After being away for 2 years on a military tour, we're coming home to find our pool in an awful shape. It hasn't been cleaned or treated for two seasons. It had about 3 1/2 feet of brown, nasty water in it and tons of leaves and sticks. We've gotten most of the debris out , and we were going to pump out the water with a submersible pump, drain it nearly empty and then clean the liner before refilling it. After reading a few posts, I realize that may damage the liner. I'm sure there are others out there who have faced this problem and dealt with it successfully. I would appreciate any advice on how to proceed from here.
