[vanreefer]

just looking for opinions on the quitest return pumps out there in the 1500-2500 GPH range

Exactly what I'm looking for :)

Check out the new Tunze silence line of pumps. They look really good. and build quality is topnotch. but the flow might be a little much (2900)

[blaster]

Probably any red dragon pump

[Bblinks]

red dragon will be the top of the list for its quiet operation, tunze is next inline, eheim 1262 a bit lower flow but it reliable and quiet. I know there are more pumps out there that fit the bill but those are the three I have used and are extremely happy with them.

The reviews of the RLSS DC5000 say it is very quiet. I'm not sure where to get it in Canada though.

reef supply canada dot com has those available. Nick is good to deal with as well.

I'm looking at power consumption a for pumps. How can some pumps get 200gph with 90 watts while others use 200 watts for 2000gph

[mseepman]

I believe the biggest difference is between A/C versus D/C control. The Red Dragons, etc...have always been good power savers versus the output.

[MarkoD]

So the dc pumps are more efficient?

Thanks! I plan on getting one soon.

Yes, DC pumps very efficient. The DC5000 I believe uses 40 W at 1320 GPH.

Mine is very quiet and only uses 40 watts at highest setting. But you would need to go to the DC10000 to get the flow your looking for.

Pump efficiency is based on many things like the type of motor, bearings, impellers and overall design. Red dragons use high quality motors, special ceramic bearings and are designed for the specific purpose. Many other pumps are just modified utility pumps or from other applications where efficiency is not of high concern. The RDs are also quiet as a result of being balanced better so they produce very little vibration which also adds to efficiency. I use a RD pump and you can hardly tell it's on even when used externally. I don't have any complaints but I think before I would invest in another one I would consider the much cheaper water blasters which seem to have similar design and specs.

I'm happy with my water blaster pump. Quiet and low wattage.

Yes, Eheim and Tunze are the ones that quiet if not silent.
I was using MAG Drive pumps for a long time with no problem but now i use Eheim because its silent and reliable.
But there are water blaster pumps out now with design similar to Red Dragon for a lot less $. I have never had one though.

Water Blaster HY 12,500 Circulating Water Pump.

Our new Water Blaster pumps are based off the same design as the Bubble Blaster pumps but intended for water circulation. These pumps feature a digital control circuit board inside that controls directional start up and RPM speeds. This smart circuit board will shut the pump off if it detects a problem.
Something never seen before on internal or external pumps is the Silicone Nitride shafts and bearings that we use. The benefit of this material is that it will not allow calcium to adhere to it like ceramic. This means less maintenance and cleaning and more time for you to enjoy your aquarium instead of working on it!
With the performance of these pumps and a 3-year warranty how can you go wrong. We offer several different models for water flow and head pressures. Check out our complete line for a circulation pump that fits your needs. You can also download the Blaster pump poster below here.
