Calcium testing question ???

[richiero]

I tested my systems calcium twice with the salifert test kit and I got 380ppm twice
And
Twice with the Hanna calcium checker
And I got 564 twice ... what do you think could be the issue if and and which one would you feel confident in going with ? Thx for any help !!!

There was a recent BRS video where they tested quite a few different test kits for Alk, Ca, and Mg.

Tested for accuracy and repeatability.

Very informative. I can’t remember where they all ended up.

Go to BRStv on YouTube and look it up. I think you will find an unbiased answer there.
