I have a question regarding a jump in TA using 2014 chemicals and 2015 chemicals. I received replacement chemicals for my TF-100 kit yesterday. I ran the the usual tests today: TC,FC,CC,TA,pH with the new chemicals.
New chemicals readings:
TC: 5.0
FC: 0
CC: 5.0
TA: 170
pH: 7.2
I was surprised at the jump in the TA. I then ran the same tests using the same sample water I used for the new chemical readings.
Old chemicals readings:
TC: 3.5
FC: 0
CC: 3.5
TA: 100
pH: 7.3
Out of frustration I used a 5 test strip and the TA indication favored the old chemical reading of about 100.
Is there a problem with the new chemicals, namely R-0007, R-0008, and R-0009?
Please advise.
