Hi all! I've been SLAMing for about 9 days and preparaing to address metal stains in my pool after that. Today I passed the OCLT, had <0.5ppm CC, and the water is clear. These were my readings at 10am.
Water Temp 70
FC 11
CC 0
PH 7.4
TA 80
CYA 20 (I'm not sure that reading is correct though. I added CYA a couple of weeks ago, but the level hasn't increased when I test and I had to raise my SLAM level from 10 to 12 to finally get the algae to clear.)
CH 40
Since I passed the SLAM requirements I was excited to start getting things ready to address the stains. I waited a couple of hours to let the FC come down a little and then I added the recommended amount of MA to take my PH down to 7.2. After an hour I added a bottle of Polyquat 60. My plan was then to let the FC drift down to less than 1ppm and start the ascorbic acid treatment. An hour or so after adding the algaecide I tested the water again. This is when I got crazy readings. My current readings are:
FC 7
CC 1
PH (I don't even know because the water turn deep purple. I've never had that happen.)
I have no idea how my PH could've changed like that and now I'm testing high for CC's...I'm at a complete loss.
