I have the apogee 510 and take my readings with pumps on. The numbers bounce around, but I figure that’s the way the corals will be living. Any reason other than steady numbers you turn pumps off?Disabled = lower numbers. It has to apply correction for taking measurements underwater
Sorry to make you redo all the measurements ! But you need accurate numbers so you know where to place corals and what to have the light set to
This all just seemed a little off to me.
I’m here all night
