Mine is a vinyl pool and the liner is about 6 years old. I would hope not to drain now, although we will need a liner in the next few years because ours is wrinkled in the bottom of the shallow end and not looking so great in the deep end from shock lying at the bottom.

A quick check this morning had a FC of 10.5 but CC was up to 6 again. Does that sound right? Am I going in the right direction?? Would it be cost effective to do the liner now?? Cost of refill is $250 plus for me.
