Quick question, I have a bottle of the flairform pH down, I didn't bother reading the label and turns out it's citric acid based.
Usually I need about 20/25 drops to bring my mix down to 5.9/6, today it's just not working, I measured some of the pH down directly and it is at 6.0, I have a bluelab pH pen but it's about a 5 weeks since calibration. Should I be trusting the meter? Seems to be reading tap water correctly and pre ph mix is about right, can a pH down just rise like that? I won't be using CA again but not sure if I should dump the mix. Bit broke otherwise I would just go get calibration solution
