It seems everyone here loves to help each other and general questions quickly become attempts to solve the issues of that individual's situation. So I figured I'd just start a thread on my own pool for everyone to help me.
Situation: winter was long, spring was lots of rain, thus cloudy water. Pool store had me buy an incredible amount of chlorine and eventually the water became clear.
Now: I've decided it's more intelligent to learn here and follow the ideas here. So I've decided the main problem I have is that my CYA (stabilizer) levels are "sky high" (over 100) (confirmed by repeated tests at the store (who never commented on it and just kept selling me chlorine) and now my own testing with a TF-100 kit).
I've tried draining and refilling about 10% of the pool (still leaves CYA above 100). For various reasons it's not practical to drain the pool further. I'm testing and getting no free chlorine but 2 to 4 combined chloramines. I've dumped ten gallons of 12.5% bleach in so far. Does anyone have a guess how much more 12.5% I'm going to need to add in to get rid of the CC?
I'm a little nervous I'll put so much chlorine in that the pool won't be fit to swim in. (and I'm going to buy out Menards for liquid chlorine).
