OK. You've got working stabilizer, but still have some chlorine demand. Continue to add large PM chlorine doses, till you hold chlorine levels overnight.

Meanwhile, vacuum up any debris, and then CLEAN your filter, to make sure you're not chlorinating stuff that you could just flush down the drain. Cartridge sticky here: http://www.poolforum.com/pf2/showthread.php?18044
