Hi,

I added 1/4 c borax last night and 1/2 cup this a.m. Brought my PH up to 7.4.
Upon testing for FC 25 ml sample turned pink upon adding 1 scoop. After 16 drops of
R-0871 still could not get to go colorless. I gave up! Is this normal and what do you do at that point? Other numbers were:

TA- 50ppm
CH 40ppm
CYA-Black dot never did go away... Maybe I did not let sample sit long enough. Did not appear to very cloudy either. I am not sure if I have enough CYA in the water at this point to register.

I am thinking about adding 1-2 TBSP baking soda to bring up TA.
