Omair February 21, 2012 Share February 21, 2012 What is your opinion on an internal return pump that runs silent? Eheim? Sicce? It would need to turn over anywhere from 350-600GPH flow. Link to comment Share on other sites More sharing options...
Ryan S February 21, 2012 Share February 21, 2012 (edited) My Mag is silent. I put it on one of these and I don't hear it at all. My sicce pump on the CS1 is the nosiest thing in my sump. I definitely wouldn't choose a sicce for silence. Edited February 21, 2012 by Ryan S Link to comment Share on other sites More sharing options...
Omair February 21, 2012 Author Share February 21, 2012 You would choose a Sicce for silence? I have a syncra 3.5 and it has a bit of a growl to it. I read that Eheims are pretty silent and produce less heat. Link to comment Share on other sites More sharing options...

I read that Eheims are pretty silent and produce less heat. typo - fixed. (wouldn't). i have heard eheim's are quiet and very reliable. never had one myself, but I'd be willing to give them a shot. a mag 5 would be 500gph, in the range you seek, and they are only like $50. also very reliable. i would recommend the dampening pad though, otherwise you might hear it.

Origami February 21, 2012 Share February 21, 2012 I've had several Eheims over the years. They've all been really quiet. Link to comment Share on other sites More sharing options...
Chad February 21, 2012 Share February 21, 2012 Quiet is a relative term, but I have been doing similar research. Above those already recommended look at the ATB flowstar series and the tunze silence series. I am strongly considering the tunze silence as a replacement for my current mag 9.5 return pump, it also has the advantage of being a low power consumer.

Quantum Aquaria February 21, 2012 Share February 21, 2012 Definitely Eheim. I replaced a quiet one 4000 which broke apart with an Ehiem and it's silent. The quiet one was almost like a jet engine when it started up and sometimes, it took about 4 minutes for it to prime and begin pumping. For future, it's either a mag drive or eheim. no more quiet one pumps for me Link to comment Share on other sites More sharing options...
