Is it normal?
This is when the main lights are off, only refugium lights are on .

Your pumps are probably generating the extra heat. Could be problem in the summer.
Do (either of you) have glass covers on your tanks? ..a closed canopy that has no vent holes or fans built into it? Both of these things tend to cause heat to build up in the tank.
Clip on fans are a good solution to drop the temp by 2 or 3 degrees. It can be placed to blow air across the surface of the water of the DT or sump. Do keep in mind it will create additional evaporation.
No glass covers. My oak canopy does not have fans on the top but the back is open. I'm getting concerned. Its barely spring and its looking like this could be an issue. I'm going to the try fans in the sump and display and see if that helps. I'm also planning on switching external pumps from the Iwaki to a Reeflo so hopefully that helps too.
Be prepared for the increase in evaporation with the fan technique
BTW where's the OP?
Lights can heat up a tank to, especially if encased in a canopy with no ventilation. What kind of lights are you running?
