The VIV mini spiral glass outflow is the perfect accessory to help slow down flow returned into small aquariums. Once the water supplied by the filter or pump reaches the circular nozzle of the piece, it spins around until it unleashes out of each side of this piece. It is quite a unique approach to providing flow to your aquarium. The spin works great when trying not overwhelm your substrate and plants with a strong flow.
