two things come to mind, one do they have an well meaning employ who notices it is getting low and tops it up?

and the second is maybe there is some syphoning going on.. do they run the skimmer 24/7 or does it shut off at times, is the overflow level slowly building up then creating a syphon effect when its all water and drawing down more than normal?

as for temp.. nop not going to notice the expansion of water.. might make a milimeter difference but not realy noticable as the tank water with heaters and such should stay fairly constant in temp.
