First off, thanks for the initial information! I have been reading this site for a while now, and was hoping to never have to ask any questions.... lol I just checked my CYA, and it's reading as if there is none at all. I'm guessing this is because of the leak I had in the liner and having to refill the pool. My chlorine level is also reading at 0 after about 6 gallons of bleach over the last 2 days. I'm really not sure on what my next step should be. Should I get my CYA level up first before adding more bleach?
