One of the bricks probably would be enough, assuming that the frags are the usual photosynthetically-enabled corals and the feeding rate is low enough. That type of corals probably emits little to no ammonia. You could skip the sandbed, as well. Heavy feeding might leave a fair amount of food in the water column, but I think it'd take a lot to overload one of the Marine Pure blocks. I can't quantify anything, though.
