thanks for the info....

I am still learning and I understand the chemistry of chlorine, but am still getting down everything else. Mainly ph and alkalinity are a mystery. If I keep reading I will figure it out someday. It is all so overwhelming and I have a small pool!!!! I kind of freaked out awhile about the whole bleach thing, because I know sometimes water is swallowed especially by the kids. But now that I understand its the same as the chlorine you by at the store I am feeling better about it.
