Thank you.
Still fighting with this thing. Got it calibrated..but immediately after the calibration, the alkalinity was WAY off to hanna and salifert (8.5 for both) while trident was saying 7.24 and has steadily been falling. I reached out to Trident and their answer was basically they will be different, live with it. Take the average difference and do the mental math every time.
Ok. i get they will be different, but when i tested the calibration solution...i got 9 vs 8.45 on the bottle (+0.55). When I tested the tank i got 8.5 vs 7.24. Is this normal? Just live with inaccurate answers as long as i can get within 1.5 dkh? Honeslty..dkh measurement was why i dropped a few bills on this in the first place. Really debating returning to BRS.
