Is there such a thing as adding too much chlorine in a plaster pool during a slam? The recommended slam level I got from the poolcalc was 20 (CYA is 50) for my roughly 23K pool. PH is 7.6 and total alkalinity is 90 if that's relevant.
My pool is pretty green and I've been scooping/brushing algae away for a week. I currently have no metal in the pool (ladder and railing are still in storage), and I don't plan on swimming in it for at least a week. So unless I'm overlooking something, would adding enough bleach to get it to say 50 (or even 100, although I wouldn't do that) cause any harm? I don't want it to drop below 20 overnight
