You can have any pump you like for a closed loop. A closed loop sucks water out of the tank and pushes it back in, like the circulatory system in your body. Just like your blood never makes contact with air, the water in your tank never makes contact with air (as it would with a sump). It flows out via tubing to the pump and right back in.

Just use your current pump, which is more than enough. You can get some modded maxijets or Tunze Nanostreams to create lots of flow that use very little space in the tank and very little electricity/heat.
Where would I set up the intake side without it making it look ugly in the tank?

Got any links to those 2 that you mentioned?
Thanks Melv!
