Relatively new to the forum. Haven't had a chance to change my signature but had a quick question about CYA. Live in Texas and we've been getting monsoonal rains down here which has wreaked havoc on chlorine levels. Have a tri-chlor canister on my system (I know...boo, hiss.....but still learning and was put on by my PB). I've been either using Cal-Hypo shock or liquid chlorine to bring chlorine levels back up rather than crank up my feeder but noticed that CYA levels have remained constant. If these rains are displacing so much water to swing my chlorine, and I'm not adding more CYA by cranking up my feeder, shouldn't CYA also go down? Or is it that CYA is only at lower depths and never gets ran off with the rain. Silly question, I'm sure, but something doesn't necessarily compute with all the rain we've got. Thanks in advance for any insight.
