Review: quiet powerful sturdy - The first one they sent me made a loud bad noise. That night I required a return. In the morning I returned defective unit and get this: the same day I received my new air pump. Thank you that was so cool. I have a four gang and a three gang valves powering five air devises and the pump is turned almost to lowest setting I used a T connector so both outputs of pump lead into one. Everything works and the pump has a very quiet pleasant tone. Best air pump by far I ever had. I have a 36 gallon and a 10 gallon and the 400 is not to big. After a week I realized the volume control nobs have markings ( dots ) that makes them perpendicular to each other.
Review: This is the one to get. - I previously used Penn-Plax air pumps, but they are difficult to come by. Most recently I've tried Tetra pumps, but of the three I purchased, they ALL had manufacturing defects that only became apparent months later. (the pump head bracket was either cracked or missing entirely) This pump is excellent. Quiet, and powerful with individual outlet adjustment. Why this doesn't show up in a search is beyond me.

## Questions & Answers

**Q: Sound wise, how would this compare to a tetra whisper, for instance?**
A: My tetra whisper hummed pretty loud.  The Eheim 400 has more of a low buzzing sound.  I keep in the fish tank stand cabinet and cannot hear it at all with the doors closed.  Hope this was helpful.

**Q: How many liters of air per hour does the pump put out?**
A: 400 LPH

**Q: Hi, what voltage is this?**
A: 120 V/60Hz

**Q: i have a 150 gallon tank. will this be okay? or what else can i use? i also use jeboa powerhead to circulate water.**
A: Should be fine. I'm using it on a 260 gal tank (that also has 2 x 2260's) to get a little extra agitation at the surface. I've got the stones near the bottom of the tank and the air flow is plenty good. If you need more detailed help I'd recommend searching for a well established forum as opposed to Amazon answers.

### ⭐ This is the LOUDEST air pump I've ever owned.
*by A***L on October 9, 2018*

I've had multiple air pumps over the years, most of them have been Tetra Whispers. When I heard this one was the quietest available, even quieter than the tetras, I wanted to give them a try. I bought one to put in my kitchen for my betta tank. This thing is SO LOUD. I can hear it over the TV. It rattles and the hum is so incredibly loud. I have it on the lowest setting. It was okay at first, but seriously no more than 2 weeks running and it was just unbearably loud. I've lost track of how many times I've said the word loud in this review. Idk if mine is faulty, but I hate it.
