I have never got my ph probe to read properly. I gave up a few month ago, but I am going to give it another try.

I calibrated using ph 7 and ph 10. My test kit and my LFS ph meter have the same value, but my RA is consistently reading .4 high. I want to hardcode the ph.min and ph.max.

I am going to start with these values:

ReefAngel.PHMin=520;
ReefAngel.PHMax=840;

If I need to adjust it to raise the reading:

should my low go up or down?
should my high go up or down?

If I need to adjust it to lower the reading:

should my low go up or down?
should my high go up or down?

Return to Standard
