Heater In sump not doing it

[jorge0912]

I have my heater in the sump and no matter what heater I have in there it dosent cut it for some reason even went to go buy a new one and still temperature is going down ...
Is a 75 gallon with a 20 gallon long sump
What can I do I currently have a 200 watt heater down there went to go buy a 300 watt ehiem and still didn’t cut it for some reason so went back to the 200 watt

Do you have enough flow through the sump? What area in the sump are you putting the heater? Does the water in the sump feel warmer than the display tank?

200W should be enough unless your house is really cold. I have a 200W heater that keeps my 125 gallon tank with 55 gallon sump warm unless I open windows when it's cold outside.

Are you using the internal thermostat to control temperature? What is it set to?

It is set to 78 degrees is the ehiem jager 200 watt and my house is 67 always set at that
Is maybe to much flow in the bottom it dose t cut it to heat ? Properly ?

Nah, flow will help make the temperature more uniform throughout the system unless you have excessive evaporation. Sounds like you could set the heater to 80°F and see what happens. Alternately, a temperature controller would give you better control over the situation. The internal heater thermostats have been known to be off several degrees when compared to the temperature indication dial.

Agree w above.. sound like maybe your 200w died or is dying and the new one is just poorly calibrated.

Well the heater is calibrated my water rigth now is at 75 degrees put it at 75 and it turn off ...hmm maybe not strong enough

Does the heater turn off while in your tank when it is not at setpoint or does it run continuously?

With the house @ 67 you will need more from the heater to keep the tank up to temp.
Either double up or use a larger heater, And double check the actual set temp on the heater, they are not that accurate from the factory.
