I tested my pool this morning before cleaning it or removing the solar cover. The pump had been running about an hour:
FC 3
CC 1
PH 7.6
TA 80
So I added 25 oz bleach according to pool math (8.25% just to bump 1ppm). I also added half of the borax to bump my pH to 7.7. That was about 14 oz by weight. Just trying to nudge it. This is based on 17k gallons not 19 like in my signature. I also threw a sock of CYA in the skimmer as I’m in the low 40’s and trying to creep up on 50.
I proceeded to clean and vacuum after adding my chemicals and cover was removed. Then I left the pump running and the cover off while I ran some errands. I came back and tested again to see if my pH and FC were at my expected values of 7.7 and 4.
My 2:30 readings:
FC 5.5
CC .5
PH 7.6
TA 80
My FC increased by 2.5? That doesn’t make sense to me… I was at 3 added a measly 25 oz and went up 2.5ppm? I’m not at all surprised my pH held. I pretty much expected that to still be 7.6.
How can my 2.5ppm uptick be explained? I’m using k-2006, speedstir and sample sizer.
