Anyone else notice this in their tanks?
The 50W Tronic heater in my 15 gallon tank occasionally sends up a bubble of air, maybe about once an hour. As far as I can tell, the heater is still working correctly, there is no water in the heater, and the glass tube is not cracked. Anyone knows what's going on?
