the advantage to external pumps is LESS heat transferred to the water. Submersible pumps are cooled by YOUR tank water!

there also isnt many submersible pumps with the head pressure rated high enough to be a return pump. i say go with the external, makes for a neater set up as well as you can have more space in your for things like a phosphate reactors, refugium, etc..
