Mark, thanks. That's an easy conversion to work with.

Part of the reason I wanted to this information is to see if a SWCG would have the capacity to administer a shock dosage of Cl. The Pool Pilot line claims to have Cl capacities of 1.28, 1.56 and 1.92 lbs. of Cl per day. My reason for considering this is that I have to depend on a pool service company for maintenance for three weeks out of every four, and they currently use Cal-Hypo for shock...which I would prefer to avoid.

Is there a particular reason, other than extra wear and tear on the cell and the time required to build up to a shock dosage that I should avoid using the SWCG to shock the pool?
