Thanks for the response Watermom. My parent's awesome neighbor is monitoring the water fill for tonight. He's shutting the hose off before bed and will restart in the morning. I didn't add anything because there was only 3 inches of water in the pool and I was afraid the bleach would damage the new liner. What should I get as far as CYA? I'm not sure that I've ever used this...but it seems like you need to know what you're doing (I've read all the links from here) to use it. I'd also like to start off with the BBB method and not add anything extra unless needed. Thank you for taking the time to help me (all of you wonderful people). This has been hard because it's not even my own pool and I really,really appreciate your help. Said it before..say it again! This site is a Godsend!! Kath
