That's exactly what I was thinking. I hate to bombard you with questions but your setup is very similar to mine. I went with my heater in the second chamber as the third chamber was always lower with water.
I'd also recommend one of these:
inTank All-In-One Aquarium Surface Skimmer
inTank Surface Skimmers remove the ugly and harmful surface scum from your water.
intankaquatics.com
Definitely makes the surface of the water much cleaner and gets rid of all the scum.
