75 gallon tank.
Canister filter.
Lighting is a single 32 watt t8.
Heater set at 78f.
Room temp at 74f.
Yesterday the tank's temp climbed to 81f. By the late evening I got it back down to 79f with a few small water changes. Today it has risen back to 80f. I know this temp is tolerable by my fish I just don't know why it is climbing so high while the room is so cool. In an attempt to help keep the temp down I have added a power head (with bubble hose) for movement and aeration. I have also cracked the glass tops a bit to let more heated air out. Any suggestions?
