I did put a bucket of stabalizer in Sunday night and Monday morning. I tested the water tues and the CYA was still low. I've been getting my water tested at the pool store for about 2 weeks now and only the last time did they tell me I needed stabalizer. I'm going back to the store tonight or tomorrow to get more shock and have it tested again. "shock" is what I should put in right? And pretty much do a crap load? I can't overdo it right?

thanks
