Looking for a QUIET pump!!!!! Help please!!!

[cashman95]

I have a 75 gallon tank, and I am going to be downsizing in order to get the "wife's approval" for living room location!!!!!

I am going to probably be going with a 50 gallon cube. I currently have an Eheim 6051 I think(around 700 gph) and while this is an extremely quiet submersible pump, I was think of maybe using an external pump like a Panworld or such for even more noise reduction....does anyone have any experience with this?

Are external pumps quieter than submersible one's?

T1 pump...very quiet, but runs hot.

Submersible pump noise if further quieted by being underwater. For a 50g cube, I would go with Eheim 1250 as the return pump. The 1250 is dead silent.

Sorry, the Eheim 1250 is what I have.....I was getting confused with my tunze nano's!

So the ehiem that I have IS probably as queit as I am going to get?

If you're not familiar with external pumps, the Panworld pumps really aren't as quiet as you might think unless you mod them by taking off the stock fan and replacing it with a computer fan. When I made the switch to externals, I was actually dissappointed at first. But after doing that mod, I'm pleased with the noise level.
Also, what Killereef said is true- the Poseidon/Velocity pumps really do run dead silent, but again they get pretty toasty and I'm not sure if I'd want to put one on a tank that small.

I dont think the external will be more quiet than the Eheim

It would be difficult to get a quieter pump than a 1250. BTW, its only 317 GPH @ 0'. External pumps are often air cooled and have a fan which obviously makes noise. Some are water cooled, and are quieter, but add heat (as does a submersible).
