The pump works good if you can keep the thing from vibrating and shaking my sump. Would not buy again!
Efficient but vibrates too much By Shark on 2/9/2017

I've been running this pump for 2 years now. For 99% of the time I have owned it, it vibrates everything while humming. The entire plumbing assembly vibrates. Im sure this bothers the fish. It bothers me. Nothing fixes it. Trust me Ive tried everything. Do yourself a favor and buy an external pump. All I can say is at least it is reliable. 3 stars for that.

This pump is a silent beast. Extremely reliable and easy to setup.
Well made! By Russ K on 7/2/2015

The pump is a solid and quiet. The "NPT" fittings work great with the included adapters, but leak easily when plumbed directly - even with Teflon tape. I did not want to go too thick on the tape and risk cracking the connection, so I added a bit of silicone to the threads and finally got a seal. Looks great externally. The shroud that covers the inlet is a nice touch to hide the fittings.
Quiet, but head height is significant. By Jim on 12/27/2014

This is a really nice quiet pump. Be sure to review the head height vs. flow chart carefully. This pump loses flow pretty rapidly compared to some others based on the height of your return.
Energy efficient, but not silent By Liz on 8/13/2014

There's nothing "silent" about this pump, it emits a loud hum like all the others (though maybe quieter? I'd like to see decibel noise comparison readings on these products that claim to be quieter). I bought it for the energy efficiency/reduce heat in the aquarium. The flow adjust valve is easy to reach/turn. Provides ample flow for a 40 gallon aquarium with a 5' return from the sump.
Excellent pump By Corey on 12/28/2013

I ordered this pump about 3 months ago after some thorough research. This is an awesome pump for the price, very quiet! The included output adapter made it easy to connect 1" vinyl tubing. Overall, I'm very happy with this pump.
