(More customer reviews)I use one of these pumps to power my Cichlid community tanks under gravel Jet system. (If curious about UGJ's look them up on Cichlid-forum)
It provides good water movement and excellent filtration thanks to the attached sponge filter. It is no louder than an air pump really and has no real drawbacks. as with all impeller driven pumps clean your impeller often and it will treat you good.
The water flow valve is also good if you, like me, like to lower the water flow in your tank at night to help the fish rest.
