Alternative Trident Calibration Solution

[Wanderlust21]

Hey all, I’m looking for alternative ideas for the calibration fluid on a Neptune trident. I’m wanting to be able to calibrate it more frequent than once every 3 months. Thoughts?

Ive been using tank water and calibrating it against manual test kits i would have trusted without the trident.

Po4 Hannah checker
No3 Hannah checker
Alk salifert
Ca salifert
Mag salifert

Works great for trends, but I do recalibrate monthly with little drift

Agree. The best approach isn’t calibration solution, but to test your water manually and then calibrate to that. Several advantages.

I have changed my testing schedule -so that it only does alk 2x a day and ca/mg 1x a day.
So I calibrate every two months.

If you order directly from them it’s fairly cheap. But you should calibrate against the solution as the optical curvette gets dirty over time so the solution helps calibrate against that as well.
