I've used Hagen powerheads in all my tanks since beginning reefing back in the late '90s and have found them to be very versatile. The amount of flow can be regulated on them, the direction of stream can be changed ~270 degrees all by moving the nozzle from one side to the other, they can be placed high or low in the tank (though I prefer them high), they can be removed easily and cleaned frequently, they are relatively inexpensive, they can easily be anemone-proofed. Gads! They're pretty darned good in my books
