I actually did the sock method yesterday, read it on this forum I was just thinking its not granular so maybe I didn't need to do this.. I will do the sock method again and will not follow follow back of container. So I will just wait to retest once all the stabilizer is completely gone from sock.You should use the sock method to add CYA to a pool. How did you add what you did yesterday?
Add the CYA by using what we call the sock method. Get an old sock (no holes) and put the measured amount of CYA you need. Tie the sock closed and either suspend it in front of a return (hang it from your brush pole works with something weighted on the deck) OR if it still allows flow thru the skimmer, place the sock in the skimmer. Every 15/20 minutes give the sock a squeeze to speed up the process. Please DO NOT follow the directions on the container of CYA to just pour it into the skimmer and don't just toss the sock in the pool as the CYA is acidic and can bleach/stain pool finishes.
