Some of the drop in your tank level (I'm not sure what size it is and therefore how much actual volume we're talking about here) could be from the skimmate, but don't forget about evaporation. Do you have an auto-top off system in place? Have you checked your salinity lately? Just some thoughts...
I've had my Remora running on my tank since day one...I've been real pleased with it, though I haven't been skimming off much of anything lately. I'm hoping that it's a sign of clean water and not a malfunctioning skimmer.
