How much Calcium do I need?

[CarlD]

You can always start chlorinating with Cal-Hypo until you reach your target.

Don't use the 48% garbage, though--use the 62-68% stuff.

Get the smaller amount so you DON'T buy too much. (sorry--typo that I fixed--C.) The increase in calcium will be gradual but definite.

HTH stuff sold at WalMart and other discount houses is usually 48%. There's another label that I can't ever remember that's 62-68%, and sometimes there's private label cal-hypo at that concentration. Both HTH and the other label are Arch products, but at least the with the other you're not buying 52% of nothing.

Do NOT put cal-hypo in an automatic chlorinator. If you get the cal-hypo tablets you can put them in your skimmer or a NEW floater. Do not pour bleach over cal-hypo.
