UK trident user here, if that makes any difference.
Since day 1 the trident has been way off for Alk - reading 9.6 when my titration kit consistently says 8.2. A calibration didn’t change anything. I figured the manual titration was wrong and allowed the trident to control dosing. When the reagent A was changed, the reading dropped to 9.0 so I calibrated again and it stayed at 9.0. Again, I left it, figuring trident must be right.
Yesterday I had to change reagents b and c, and now they are both way off. Again, calibration hasn’t fixed anything. Red Sea Titration tests say calc 420, mag 1320 and trident says calc 330 and mag 1462.
I'm at a loss. I keep blasting through calibration fluid trying to get a reading that matches my manual titration, but can’t. I’m now out of calibration fluid.
As of right now my manual tests (Red Sea pro) are:
alk 7.56
calc 420
mag 1320
trident:
alk 9.2
Calc 332
mag 1462
Im tempted to calibrate to my tank water manual readings but this kinda defeats the point of spending big bucks on an automated tester and dosing combo!
Help!
