Cal Hypo Change

[chem geek]

I corrected my previous post because I am such an idiot. I had already put a percentage of 73% for calcium hypochlorite in my spreadsheet which is why I thought it would produce lower available chlorine. I was wrong...dead wrong.

So, calcium hypochlorite and chlorine gas are nearly equivalent with regards to available chlorine. So if you get 65% calcium hypochlorite, then this is about 65% available chlorine. Sorry for misleading anyone earlier.

I believe that, in addition to WalMart wanting a lower price point and HTH giving it to them, the other reason for 48% is warehouse safety. From everything I've read, Cal-Hypo is the most reactive of the common chlorinators we use. I also believe WalMart had a major warehouse fire due to something or other with 68% cal-hypo.

I bought a bucket from Leslies, on sale, and it's 73%.
