Most Reliable, quiet and *cool*

For a return pump, from sump to chiller to tank:

Rio 1700
Quiet One 4000
ESU, other?

HAS to run cool and be efficient. Which pump do you like?

Take a look at Eheim. My research indicates that this brand is the best (cool, quiet, efficient) for my return pump application. Could be for you, too.

I like the Eheim too. Runs surprisingly cool, quiet, and reliable. Run from the Rio as fast as you can.
