CYA 30
FC 3.5
CC 0
TA 190
pH 7.4
I thought I had mustard algae and slammed. But my FC wouldn't hold and CC continued to read at 0. My pH goes up every day, I've had it at 8 and higher for the last 3 days, add MA to drop it and it goes back up. And, I did have consistent CYA of 50 and we've been hit with some rain. That's when I noticed what I thought was mustard algae so I checked CYA and it was 0! So I got CYA up and started slamming. But something's not right. If it were algae there would be concentrated chlorine killing it, but there's not. Please help
