Thank you, that makes it even easier.

I also had a few questions regarding the cover. I haven't had the cover on at all while we've been trying to fix the water. The weather has cooled off a bit and it's way too cold to swim in now. So my questions are, is it ok to put the cover on when I've been trying to maintain the shock level at 15? Would it be ok to leave the cover on all week while we're gone and just have her move the cover enough to add the bleach at the return jet?
