The reason for this is that heaters bring water to a certain temperature by means of a thermostat on the top half of the device. The thermostat turns on when water temperature is below your specified setting. Then when the water gets to the desired temperature the thermostat turns the heater off until the water cools down again.

When you place a heater vertically in a low-current area, water that has been heated by the ceramic at the bottom of the heater rises directly up rather than irculating the tank. The thermostat senses the heated water's temperature and turns off while the rest of the tank stays cold.

There are 2 solutions that can be employed to fix this, one or both will work:

1) Adjust the heater so that it is on a diagonal/tilts to one side.
2) Increase the water flow next to the heater so that the warm water is blown sideways instead fo upwards.

I have had this problem with submersibles in low-current tanks and tilting soves it every time.

THANK YOU! I just tested in my shrimp tank and its working much better now, think the way I had it positioned before the lights messed with the actual thermometer of the heater

does everyone suggest completely submersing their heater? or leaving the top part out of the water?

That depends on the type of heater. If a heater is not designed to be submerged then obviously you'll blow a fuse. If you use one of those Stealths then you'll want to submerge it.

Yes, it entirely depends on the heater. If it's not designed to submerge then don't, you'll ruin it. If it is then you must submerge it and keep it submerged, if you don't you'll ruin it. That's something to remember during water changes, if the amount of water you are removing will uncover your heater then unplug it. Or just unplug it to be safe. My QT tank is small enough that a 5 gallon water change will expose the heater. My 48 is tall enough that changing 15 gallons won't mess with it.

If you bought a submersible, yes. By law, all plug-in equipment (even submersible heaters) in Canada and maybe the US are required to have a 'water line'. If you buy a fully submersible heater do not heed this 'submerge to' line.

Wow really? I have a stealth heater but was worried about putting the cord in the water. I placed it in my tank so the dial sticks out of the tank. You're saying I have it set up incorrectly?

Yes, you want that heater completely submerged. This also brings up another point. How many of you have all your pumps, heaters & lights hooked up to a GFI (Ground Fault Interrupt) outlet? If you don't you should. This will prevent you from getting an electrical shock should equipment fail or accidently fall into the water; especially when your arm is in the tank.

Including putting some of the cord under water? P.S. I do use a GFI

Yeah even the cord. IF it is submersible!
