thanks! the pucks and super shock that came with the pool are the same ingredients, just slightly different %age of available chlorine listed. my plan had been to use the puck continuously and toss in some extra granules from the bag after the nephews swim (doubles our usual "occupancy" and triples the number of stinky boys in the pool, lol). the stuff that came with my pool are as follows:

*the pucks are called hth 3-in-1 chlorinating skimmer tablets. calcium hypochlorite 47.6%, no copper listed, minimun available chlorine 45%.
*hth super sock 'n swim. calcium hypohclorite 52.0%, no copper, minimum available chlorine 49%
