I think you've figured out the poolstore thing. There are levels where calcium is an issue, even in vinyl pools. Go to Ben's tips on Poolsolutions.com and read the one about calcium in vinyl liner pools. I don't know firsthand about it, but whatever Ben says, I believe because he hasn't steered me wrong yet.
