All-
I REALLY need to get a quieter pump. Right now I have a Coralife Turbo-Sea 1270 Aquarium Pump which pushes about 1200 gallon per hour on my 180G. My overflow can handle a lot more (it is the DART overflow from Glass Holes which can handle a Reeflow Dart pump which I believe is 3600 GPH), but I did use clear silicon tubing from home depot for return lines, so not sure what PSI those can handle.

I would like to maintain at least 1200 GPH (or go higher if I can) with a similar external pump, but one that is as SILENT as possible. If that means water cooled and a chiller needed, I am OK with that.

Does anybody have any good recommendations? At this moment I am actually thinking about the ReefFlo Dart Pump: http://www.marinedepot.com/ps_ViewIt...4&child=MM1136

Thanks for any advice!
