I have owned a Trident for several months now and love the idea. I also realize there is some margin of error in all hobby grade testing. However, I am driving myself in sane with the Trident because my CA and All always seem to be low. For example, ALK currently reading 7.88, Calcium 398. Cross checking a few times with a Hannah meter for Ak and Salifert for Calcium shows 8.1 all and 450 calcium. Magnesium on the trident always seems to be pretty close to my Salifert test.
The trident is calibrated to my Hannah/salifert test using the tank water method. If I re-calibrate, it will seem ok fora. day or two then start wandering off again. Does this seem like too big of a difference given the accepted margin of error on tests? I'd Leo to one day trust it enough to drive my DOS pumps, but with a 50 point difference in calcium I don't see that happening.
