I have noticed that the water temperature in my aquarium drops to about 74 degrees F during the night. Normally, it is at 76 degrees, and I've never really seen fluctuations. It is only in the morning that the temperature has dropped.

I know wide spreads in temperature are harmful to fish, but what about 2 degrees? Should I be concerned about my heater?

Do you have MH or PC lighting over your tank? That would definantly do it. How come your temperature is so low anyways?

How big is your tank and what size is your heater? I'd try to raise the daytime temp a couple of degrees - up to 78 or so. Is your heater just having trouble keeping up?

It's a 46 gallon tank with a 150 watt heater. Should the temp be up around 78 or so anyways? I have been reading that higher 70s are good for fish, but the folks at my LFS swear that 76 is best.

150 w should cover you, but I personally keep all of my tanks, FW & SW, around 80-81. I'd hike it because a) I don't think the lower temperature is good for inverts, and 78 certainly won't cause any problems; and b) the temperature spike is much harder on them then upping the permanent temperature a few degrees.
