#1. get it to read consistent
#2. STOP trying to get it to read the same as a Hanna. It doesn’t matter.
Once it’s reading consistent pick a setting and stick to it. The idea is to be create a stable steady environment for your corals.
For instance, I try to keep my Alk at 8.1 according to the KH Director. Stability is key.
What do you consider consistent with the KH? +/- .2? Just curious. Thanks!
