This pump is not worth the life of your fish. Each one lasted about four months.I removed the cover and discovered just how cheap this thing is.

"Loud and works well."
As stated, it does the job, however my other pump (Tetra Whisper) is far quieter and also does the job just as well.

Pretty quiet, and very reliable. I like being able to adjust the flow aswell. Little pricey though.

"quality you can count on without the noise"
I currently use 5 of the 100, 200 and 300 models to drive sponge filters and airstones in 7 tanks. The pumps are effective, easy to maintain and quiet.

I will typically use one of these pumps to drive sponge filters in two tanks. I like the adjustable output that the model 200 and above have. This makes it easy to adjust the airflow going to the sponge filters.

I replace the diaphragm and valve block about once a year when the output begins to diminish. These parts are inexpensive and easy to install. If your LFS carries these air pumps they should be able to get the parts.

My power filters are louder than these air pumps are (although they made more noise at first). These pumps may cost a little more than other brands but they are well worth it in my opinion and I wouldn't use anything else.

"Definitely not quite, and only somewhat effective"
It's easy to use and inexpensive, but so what? I have no idea how they can claim it is silent and I guess I'd say it works, but nothing to write home about.

"Never again"
I've bought two of these over the last two years and both are now dead.
I have no idea what happened, it was def not water damage and I only had them running through maybe 4 feet of hose.
They didn't move as much air as my Tetratec Deep Water either, and that was cheaper.

[email protected] 42.99 I thought that a higher priced air pump would produce more air. Was I wrong! It is quiet but when it doesn't push much air it shouldn't make too much noise. [email protected] 19.49 pushes double the air at half the cost and at the same noise level.

"Mine's Quiet"
I have had a Rena 400 for about 3 months now. Puts out a lot of air, and I can't hear it unless it's hitting something inside the cabinet. Still wish they still made Silent Giants though. Now that was an awesome, durable and quiet pump.

"Quietest airpump ever? I disagree..."
I bought the smallest airpump in this series. The airstone it was running to was maybe 3" underwater.

It wawsn't all that quiet to begin with. Within about 24 hours it was as loud as any old airpump you pull out of the closet and wrap in a towel.

I bought it all of 3 weeks ago, and its currently wrapped completely in a towel, and I can still here it around a corner and twelve feet away.

Not to mention, as someone else already said- their air output is very minimal. Which isn't really what most people are after. In my experience- those new suspended motor tetra pumps are quieter and output 2x the air at the same 'rating' (ie made for 'ten gallon tanks)

There seems to be bad quality control or something "Mine is so quiet!"

"Mine's so loud!" "Mine's kinda loud..." etc etc. Everyone has different noise levels from the same product... that can't be very good.

this is a very good air pump: PROs: it is VERY, VERY, QUITE. CONs: it is a lot more expensive that other brands. also the air pressure it not as strong as the Tetra brand too. I have a Tetra Whisper in my other tank it was half the cost of a RENA but it is lot louder. so you see what i mean???

"Doesn't match up to rating"
Very dissapointed. For a $50 pump, the Rena 400 doesn't even come close to pushing the kind of air pressure it's rated at. I'd be surprised if it was half. This filter easily outclassed by the Wisper 60 at half the price. Even tried rebuilding the pump in hopes of better pressure....not much help. In the smaller pump range I'd recommend the Wisper 60, or any of the Tetra Deep series. For larger whole wall of tanks setups I'd go for the Dolphin AV-50.

"dead within a year"
this air pump was fantastic, until it died within a year! i have this cheap hagen that's been around for well over 4 years, not as good, cheaper, but lasted a heck of a lot longer! i'm just shocked, i really liked this air pump, can't believe it was just a piece of junk.

I wouldn't say this is quiet, but not too loud either. It's powerful and does the job. I like the functionality and usability of this product. Adjustable knob allows a user to set a desired flow of air to the airstone.

"It really is quiet..."
The Rena Air 200 I purchased is easily 5 times quieter than the $7.00 one I got from Wmart. I can barely tell that's it's on. It doesn't initially seem quiet when you first plug it in (while you're holding it), but once it's where it's supposed to be (where ever that may be for your pump), it's really nice. Remember it's not SILENT as in "no noise". But compared to other pump's noise levels, it really is worth the price of admission.
