I have a 2 month old set up and have put the heater in the tank. After scrolling through some of the pics on this board i noticed some heaters in the sump. I would rather put the heater in the sump so it does not clutter up the sight of the tank.
So, my question is does the entire heater need to be covered in water? i think my heater is about 12" long, but the sump is only about 7" at it's maximum.
