They do the job By Earl on 9/13/2012

I have two of these on the sides, toward the front of my 50 gallon tank and they are perfect. They provide enough current that is keeping my corals happy but not so much that it is blowing sand and corals all over the place. I have two larger ones on the side toward the rear and this seems to work out perfectly. They also aren't so big that they detract from the beauty of the tank.

I have used this pump now for a number of months and highly recommend it. The entire unit--particularly the mount--is well built and is is almost completely silent.

Absolutely wonderful in my 7 gallon nano tank. Has been working flawlessly for over a year.

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 4/30/2012

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 2/20/2012

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 7/14/2011

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.

This powerhead hold ups to its name as nano suggest to mod to increase the flow.
