The temperature in the sump should keep all water in display consistent then
Yes. The downside is that if your return pump fails (but not your heater), the display portion will eventually cool off.

Thinking about removing display Heater and keeping only one in sump what do y’all think
Is the heater controlled by a separate temperature probe and controller? If so you'll want to also have the probe in the sump, separate compartment to the heater and upstream from it.

If you have the probe in the DT and heater in the sump then if the return pump fails you'll overheat the sump.

I have one big one in display and one small one in sump. I’m thinking of keeping just small one in sump because the eurobrace on tank interferes with suction of display heater on glass
