Mustard alge??

[conductor500]

Ok, pool water to 10 ml line, added scoop of powder, dropped 1 drop 23x to clear red color added 5 drops #3 solution and color remained clear. Checked it 2 times readings were the same.
Does that mean:
FC 11.5
CC 0
TC 11.5
Do these #'s look right??

Oh, my PH. is at 8.6
what could have raised this from 7.4? All I added is bleach to shock levels
