Tamara
Wow! The name says it all!
This is like night and day compared to the pump that came with my 16-gallon Coralife Biocube! That thing rattled and buzzed for nearly a year before I finally got fed up and replaced it with this. There is a gentle hum from this, that you only hear if you’re standing within 3 feet of the tank. And it moves some serious water!!!
I think my fish are happy to have a quieter tank, but also irritated with me that I didn’t do it sooner!
