Which calcium reading should i trust?

[jlowe7]

I have been trying to lower my calcium levels because my hanna checker keeps reading 600 which means its over 600 because that is the max reading and it wouldnt go down after 5 days. So i decided to test it on my salifert test kit and when i did it read 450. Which tester should i believe?

Sailfert if it's a new out of the box test. What's your calibration like with your Hanna? It might need a clean aswell because calcuim can harden out of water.

Unless you overdosed greatly, 600 ppm is unlikely. Id believe the Salifert. I’m also not a fan of Hanna calcium.
