My local wal-mart carries "Shock" and "Super shock". It's just Calcium Hypochlorite in powder form. (I don't have it in front of me, but I think it's about 40% and 50% respectively) I've calculated that unless the Sam's Club bleach is on sale for $1.49 or less (and then I use bleach), it's just a few pennies more to use the Shock instead of the bleach, and much more convenient.

Am I causing myself any problems? I am a little worried that the 40% solid weight CalHypo won't translate the same as the 6% by volume bleach.

I promise not to use PHUp! and to only use pucks when I go on vacation.

Am I forgiven?
