Coralife 05146 SL-65 Super Luft Air Pump

I purchased this air pump seeking a pump that would be able to power a large set of airstones at a depth of 3 feet. Many other pumps that I tried were not quite up to the task.

This pump is louder than a standard vibrator pump, but if you need a heavy duty device that pumps a lot of air, then this is the one.

Update: 8/18/2012 I'm sorry to report that the pump has failed after 8 months of service at a depth of 3 feet. Although the pump was loud, it was acceptable given the volume of air that it pumped when new. However, over time it got louder and then lost the ability to provide even a meager amount of air at a depth of 3 feet.

I have gone through several aquaruim air pumps in the last 3 years. The last one was a whisper 100 which was only about half the price of this one and lasted about 6 months. The whisper pump was really not any quieter than this one. This pump puts out alot of air and can be adjusted easily with the valves on the included manifold. It is not silent, but it is not realy loud either. If you want a silent pump, this is not for you. If you need good constant air it will deliver. I have had this pump for about 1 month now with no issues.

I read the reviews and I knew that this would not be "quiet", but I was not ready for how loud it truly is. Maybe it does a great job. Maybe it's better than diaphragm pumps...that's all well and good, but if you can't be within 30' of the tank because it's so loud, it is a waste. We put this in the tank cabinet and turned this on with the air valves off. The sound that came from the pump was the equivalent of a loud TV. There is no way to have a normal conversation in the same room as this pump when it was running. As a test, I turned it on, closed the cabinet, and made a call from my speaker phone that is about 10' from the tank, and the person on the other line asked me what the noise was without me prompting them. So, while this may very well be a solid product for what it is supposed to do, it is just too noisy to be practical in most situations.

We are a nightclub with 2 large bubble walls. All locally sourced air pumps, even so called high output/heavy duty models, did not generate enough air power to run our bubble walls. This Aqueon Coralife does the job with ease. Thanks.

Works really good, but it is VERY loud. You can make it run quieter by running a 3/8ths inch air line from the intake port on the pump to somewhere else. Preferably with cool air, as it runs quite hot.

Very well made and I knew it was loud, so I'm not going to knock any points off for that. It doesn't say anywhere on the box that it's a quiet pump, so there you go.
