...your Apex pH probe that is.
With a new sump, I recently noticed that if my pH probe gets to be ~2.5-3" deep in the water, my pH reading drops almost .2 when the pump stops and water level rises about another inch. If I keep it at about 1" things are stable, as the probe is then only about 2" deep when the pump stops.
Is this normal or do I have a probe problem?
