I'm getting conflicting readings with my new TF-100 test kit.
ph = 7.2
TA = 80
CYA = 70
FC = 24
CC = 2
So far so good. The TC is what I expected, as I shocked two days ago to recover from algae. (And the TA sample turned to yellow instead of red, which I understand also indicates high chlorine.) The problem comes when I measure chlorine with the included Taylor K-1000 kit: 1 get a reading of only 1 (very light yellow). To double-check, I got out an older basic test kit I have, and with it I get what I would expect -- off the scale, very dark yellow/orange.
The water is blue and clear.
Anyone know why I get the apparently erroneous reading with the K-1000? (The kit is only about a month old.)
Thanks!
