Thanks for the info PoolDoc! I'll check out the link. What can I do about the white stuff suspended in the water? Not sure what I can use if I use Bleach instead of chlorine tabs. I tried Super Water Clarifier and Sink & Sweep before I started the Bleach. The white stuff sank but you can't vacuum it up. It's real fine and starts floating around. Not to mention that I can't vacuum to waste. I've got 4 filters so I change several times a day lately. Will the white stuff eventually filter out?

Thanks again!!
