CYA was stable at 70 Throughout April and May. June had a lot of rain and CYA dropped to 40 on 6/21. I added 4 lbs of stabilizer and on 6/24 CYA was back to 70.
In June there was a good amount of rain and I had to drain a about 3" from the pool. I was surprised that 2" would have dropped CYA that much but. It also dropped CH from 330 to 310 and I added Calcium Chloride to bring it CH to 350. The pool has been crystal clear since day 1.
Today I did the full array of tests at 10:30am and CYA was back down to 50 (reading between 40 and 50). I've discharged no water since June and CH is still stable at 350. What gives?
