Ok, now I am pretty sure I have some sort of leak. The water level is dropping about 2 inches overnight. My question is now how do I find it? I've checked all the plumbing above ground and there doesn't seem to be any obvious holes in the liner. I'm going to try leaving the pump off overnight tonight to see if that makes a difference. I'm also gonna call the pool guy to come and try to pressure test the lines to see if he can find anything. Any idea on how much that cost?

Thanks,
Russ
