When I opened my pool last week, I scrubbed it up, schocked and balanced everything. My cya was reading really low for some reason (20 or less), so I added enough stabalizer to get it to around 40-45, didn't want to overshoot. I was out of reagent, so I went ahead and ordered more. Over the course of this week, when I tested the chlorine levels, I noticed they were not holding at all during the day. I saw no visible algea, but decided to shock yesterday and last night. The chlorine levels held overnight. I went ahead and tested my cya again, even though it hasn't been quite a week yet (5 days close enough, right?) My reading was still only around 20-25, so I just added enough to get it back up to 40-45. I guess my question is, was it too soon to add more? I was going through the bleach like crazy just to keep the chlorine at a safe swimming level. I really don't know where it went, but I have read on here that sometimes it just disappears.
Here are the rest of my numbers:
FC 16 (from shock last night)
CC 0
ph 7.5
TA 100
CYA 25 or so
