Hi,

Sorry for the late reply.

ORP measures the Potential difference between the amount of Oxidizers and Reducers in the water.
ORP readings depends on a few factors, such as the type of ions present, the pH, the amount of dissolved oxygen and organic loading in the tank.
With consideration of the above factors, under normal circumstances, Hydra accelerates the breaking down the organic nutrients(reducers), so there will be more reducers being detected by the ORP probe, so ORP dropping reflects this action happening.
