Absolutely perfect for my 15g tank. Fish love it and play in it, very quiet, and isn't too powerful.
Compact and LOUD! By Gianni on 4/30/12

I own a few Koralia's (2x 1400 and 1050) so I thought I would try this nano for a dead spot I have behind my rocks. The egg sized form was perfect as I needed something that would fit in a tight location. After plugging it in the first thing I noticed was how loud it was. It sounds like a distant gas powered leaf blower. My 1400's are pretty quiet. You have to put your ear to the glass to hear them. Not with the 425. I can clearly hear it buzzing 5 feet in front of my tank. I will try taking it apart and seeing if I can quiet it down but so far I'm not impressed.

I've had this pump about 8 months now. It's small living up to its name, but small in performance it is not! This is the main powerhead in my 20 gal tall reef, and it does a good job . I wish I had two!

Good water movement for a nano. By Frederick on 2/21/12

I have two of these nano pumps running in my 29 reef. The magnets keep them from moving and they run extremely quiet. As other reviewers have commented, the cord tends to pull on the pump turning them and making it difficult to maintain the angles I set them at. I would say that these small units are a good value for the money.

Good flow for a small pump By Chris H on 7/14/11

I picked up two of these little pumps. They run very quiet and the magnet holders keep them from moving up or down. Like another reviewer commented, the cord tends to pull on the pump turning it and making it difficult to maintain some angles. All in all an excellent value.

I added this powerhead in my 38 G FOWLR to increase the flow in one section of my tank. It does exactly that and wow it's small! the nano lives up to its name.
This is a very good product but due to the small size of the powerhead and the thick electric wire that is used, it's hard to keep the powerhead pointed "straight" because the wire on the back keeps pushing it to a direction. hard to explain but hope you get my point. either way to biggie!
