Hi, I am getting ready to add stabilizer to my pool. I wanted to ask a couple of questions before I do though. Based on 20,000 gallons the directions say to add 4 lbs. after dissolving in bucket of hot water. Broadcast over surface of pool. Okay here are the questions......Is this the proper way to add? It is granular. Will it hurt the liner? How long do I wait to add chlorine after stabilizer? How long to keep filter running after adding stabilizer? Okay I think that's about it. Your help would be greatly appreciated. Thank you, Patricia

Most of us like to add CYA by putting it in a sock and hanging it in front of a return. CYA is very slow to dissolve and can take up to a week to do so. Even trying to predissolve it won't do much for you. You don't want it sitting on your liner on the bottom of the pool so I would think that the sock method is the best way to go for you.

After you add CYA, you do not have to wait to add chlorine.

If you predissolve and broadcast, I'd keep the pump going 24/7 for a day or two, and brush a few times a day to keep any granules off the bottom. If you use the sock method, just run the pump as normal and it will eventually dissolve.
