I normally use bleach to chlorinate my pool, but my water is very soft (almost no calcium). So, I was thinking about using Calcium Hypochlorite for a while until my calcium gets up to normal levels. I want to do a cost compairson of Sodium Hypochlorite (5.25%) and Calcium Hypochlorite (65%) but am unsure how to compare the two. The main thing I need to know is how much "available chlorine" is in each product. Since the chemical forumulas are NaOCl and CaOCl, are they one to one equivalents? In other words does 1 pound of NaOCL provide the same available chlorine as 1 pound of CaOCL? If this is the case then the conversion will be easy.

Thanks,
Jim
