I just tested
FC bright yellow above the .5
TC 12.5 I think I did the drop test 25X.5, did the CC test water stayed clear so no CC. If I'm correct my tc is 12.5 right?
Not sure if I have enough in my kit to do another full drop test. I have to reorder some tomorrow.
How often should I check CYA? Trying to figure out if I need a refill on that also. I have enough for 1 more test.
I'll update my number again in the am
