I have a 55 gallon tank that i just set up.
I am new to the hobby of keepin tropical fish only had goldfish before in a small tank. I have a Emperor 400 runing on the left side of the tank and a bubble wall on the other side i was wondering where to place the heater its a 200 watt submersable unit. i have it on the right side of the tank now and set at 79 and the thermometer that is on the left side of tank is showing 76. how long do i wait before temp is stabalized and is my heater in the optimum spot. the tank was at 50F yest at about 4pm and is at 76 now but the heater does not stay on all the time is this normal

I usually place my on the opposite side from the filter when I can, but don't really think it's critical. Just may get better control without the water movement from the filter. Also they never stay on all the time, so yes it is normal. Mine are also a couple of degrees off, so don't worry if it's not precise...just adjust accordingly.

Dennis, it depends on how well your circulation and filtration works, also. Otherwise, the only thing that transfers heat is direct conduction to the water, and some very limited convection, which will only keep a layer of warm water in the vicinity of the heater and not spread it out. I tend to put the butt end of the heater either near the intake or the outake of the heater, with the actual heater not in physical contact with anything except water.

Oops, typo. It should read "near the intake or outake of the FILTER" not "the heater". Sorry.

Do you have to submerge the heater? I have an Ebo Jager and would like to keep the top at the top where I can adjust it without going in the water.

Yes,I submerge all my submersibles. If you don't put it down too far, you can adjust it with only getting yourself a little wet! When you do water changes the instructions say to wait 10-15 minutes before exposing it to air, so I don't think you can get away without having it submersed.

Submerge all submersibles to the "minimum water level line" or above, otherwise you risk damaging the thermostat in them (allowing them to stay out of water and in the "on" position also risks cracking the shell). If you would like to just keep the top of the heater just slightly out of water so that you can leave the knob in the air, that's fine, but you have to watch the water level with evaporation (try not to only top off water unless you use RO, because it will increase hardness over time; I usually just do a water change when the evaporation makes it get too low).
