The kids were swimming in the pool and splashing alot of water out of the pool and I also backwashed so my water level dropped significantly. I added some water to bring back to proper level and rain also added some more. I tested CYA yesterday and it registered around 30. My goal is to keep it at around 75. I am planning to add granular stabilizer to bring the CYA back up to my goal number. Based on pool math, I need to add 37 ounces of stabilizer. My pool store only sells it in powder, not liquid. I read that I need to put the powder into a sock and leave it in the skimmer basket and run the pump for 24 hours and no backwashing for a week. What type of sock am I putting it into? Panty hose type or regular cotton socks?
Also, my daughter is having a pool party this saturday. Should I wait till after the party to add the stabilizer or is it ok to add it right now? Thank you
