Specifically, their "Sock It", shock-n-swim formula vs. their "Chlorinating Granules" product.
Both list 47.6 Calcium Hypochlorite as their active ingedient. Both say Available Chlorine 45%. Neither specifically list the other 52.4% of their ingredients.
Both also say they "Will not cause overstabilization", so I assume that means neither has CYA in the formula.
I bought a bucket of the Chlorinating Granules today and plan to use it to shock my pool tonight and raise the CH as well. I found the PO's stash of Sock It when I got back from Home Depot.
Which product should I use?
