I have been looking around for some pool shock online , most if not all brands like HTH and such only seem to only have have 52 to 56 % calcium hypochlorite.
I would prefer 60 % or better for potable water JIC, and I do not see anything at wally mart, home depot, ect.
Am I missing something? or is 56% the right number.
or is there and alternative I am overlooking?
Thanks to any that can help.
