Hello everyone, I have a 27 x 52in above ground pool and was thinking about draining it to get a really good clean to the liner, last year we had some trouble with LG and had a hard time keeping stuff clean for some reason... I was wondering if it was a good idea to drain it to clean the liner first off and how low we can drain it safely without compromising the walls of the pool. Also is there any suggestion on what would be a good cleaning agent for the liner?
