NEW DESIGN! 13W UV Sterilizer Adjustable Pump Filter 150 gal Aquarium Fish Tank
Moves lots of water. Don't know if it's sterilizing or not.
Works good at moving water. Flow is adjustable and you can change flow direction. Good quality. Bulbs are replaceable. I'm happy. Just don't know if it's killing anything I want it to kill. No green water at this time either.
