1 week ago I calibrated the trident then a day later I changed all 3 reagents. My CA on the Trident has tested really high since Where before I calibrated and changed it was in the low 400’s.
My CA on the following just tested again, and it’s registering high on Trident for a week.
Trident 535
Hanna 426
Red Sea 370
So what gives? Some corals aren’t happiest they’ve been, thinking the CA that high might cause it. But what do I trust?
I guess I can stop dosing CA and see what happens when Trident is in the right range. I read the issues with the Hanna CA checker and following all the instructions, not using distilled, but straight RODI just made at 0 TDS. Maybe I’ll not pay attention to the Hanna since others have ditched it. Maybe I should get a 4th test kit, Salifert for CA?
Have others had this issue and went with Trident no matter what? I just want to go with one test.
Here is the ALK which I think is within the margin of error and am happy with:
Trident 7.78
Hanna 8.1
