i just converted to sump filtration and now have a consistent water level in my tank. i haven't been covering my tank. i have two fire eels (i know an odd tankmate for cichlid) and one recently became an explorer. i found him eating carpet around midnight. Found him in time; he is well. Consequently i had to put the glass back on the top but now my temperature is fluctuating too much. Any ideas how i can handle this? Thanks in advance

Thats interesting that the top on the tank would affect your temperature that much. Is your room temp high such that with the tops on you are trapping heat from the lights and not radiating it into the room? Perhaps the thermostat isn't working on the heater. In my sumps I usually put the heater in the sump not the tank, but that is for cosmetics reasons not performance reasons.

i have the heater in sump too. i like cosmetics too. :thumb: That room is warm but the heat only seemed to start fluctuating since i put the glass on the tank top. i even moved the digital therm in the tank and it's still up.

sounds like maybe your thermostat in the heater is malfunctioning. before you put the tops on the heater was doing all it could to keep up with evaporation but with the tops on the malfunctioning heater wins? I have 3 sump setups with lids on the tanks and have no issues so I would look to the heater.

I think you are right. i noticed earlier today the heater turned on when i had it set for 70 degrees and the temp was at 81.5. i'll pickup a new one tomorrow. Thanks for the responses.
