Return Pump

[JohnM99]

The Velocity T4 is by far the quietest pump, as far as I know - it is uncanny how little noise it makes - 1700 gph only, though, at 0' and not pressure rated.

Dolphin Ampmaster are really good pumps, too - reasonably quiet but a bit more $$. Sequence pumps are really good, high flow pumps also.
Iwaki and Blueline are very similar to each other - the larger sizes have a fan, and the fan makes them noisier but they are built like tanks and will last forever. I have a Blueline 70 I am not using because it was too powerful for my returns. It is pressure rated and puts out 1700 gph which, even with 12' head pressure was swamping my dual 1.25" drains. The thing is built like a Hummer.

Maybe a couple of Velocity T4s would do it - but the Sequence or Ampmaster are probably more suited to your tank size.

Also, don't try to buy any of this stuff in Victoria - I have got most of my stuff from J&L in Vancouver, and from the states - Premium Aquatics, Reef Geek and Marine Depot, etc.
