All this talk about Eheims and Filstars being so so silent... are you guys talking about them when consealed in a cabinet behind closed doors, or outside any cabinet? Of course they would be much quieter in a cabinet.
Wow. I've an Eheim Pro 2, and it's quiet but not 1200- shekels- worth-of- quiet. [Israeli currency]. I mean, it hums (quietly)(But not absolutely quiet).
I have two of the 2213s running out in the open in my bedroom, and there is no noise whatsoever. You might have something loose in yours if you can hear noise. I've read something before about the ceramic impeller shaft cracking and causing a bit of a rattle. That part is replaceable. Just a thought. :huh:
I have pro II 2028 that's about 8 years old and it's as quiet as ever. I have a fluval 404 next to it and I can definetly here the fluval humming from a few feet away.
I have two eheim classic 2215s going now for almost four years and they have been as quiet as can be. I just put the same filter on another tank a couple months ago and that one is just as quiet. In fact I have to walk up to them and check them to make sure that they are still working. That's how quiet they are.
