 Incredibly Quiet, Pretty Powerfull Aug 06, 2009
By Luna
This is the most powerful quiet pump available. Hands down. Now, it's not the most powerfull available, but then again, who wants a turbine running in their house that they have to listen to all day? This pump is plenty powerful (only mildly less than the louder models) and a great choice. Believe me: I've tried them all. Pretty long lasting as well - My last one kicked the bucket after 4 years of hard work.

Quiet as a... super quiet pump Jun 21, 2008
By C. S. Jennings
"children's illustrator & author"
I've never had a pump this quiet. I've had it for two months now. It really is almost silent.

Super Quiet with decent airflow Mar 04, 2010
By R. Calabro
"slipgate"
This pump was purchased to replace a VERY noisy pump (but very high output). I love the Rena 400! It is VERY quiet and puts out decent air from its two outputs. It could put a little more air out but my 135 gallon tank is 24" deep and it runs the airstones pretty well. No complaints at all from this pump!

 Noise producer Apr 01, 2011
By PAVEL S VESELOV
There are two reasons I thought it was a good idea to buy that pump. It was advertised as "silent", and it promised "powerful aeration". This pump gives out only 4.35psi pressure (on each nozzle, but pressure doesn't add up). I wouldn't call this "powerful". Notice how there is no mention of the pressure parameters in the product description. That's not really that important, or that bad, but the noise... The box features nice icon of a girl with her index finger by her lips, but in truth, she's probably gesticulating "don't speak, I won't hear you anyway because this pump is so loud". Really, this air pump is louder than my water pump, which is pretty loud all things considered. I'm seriously buying myself a dB level meter just to see what is Rena's definition of "silent". I estimate this pump produces at least 30dB of noise. I guess by now I should know better than to buy anything that says silent, but omits the noise level on the box or the technical sheet. And on top of all this, the check valve included with the pump *whistles*. I first thought that whatever -- the whistling will come out of the submerged terminators and would dissipate in the water, but it's still sometimes quite audible. I'm just glad my fish doesn't seem to mind.
