* The venturi system draws fresh air from outside the livewell and injects tiny air bubbles into the water flowing into the live well. * With the aerated water entering the well at a lower level than with traditional spray heads, the entire well is more thoroughly aerated. * The reduced restriction of this fitting allows more water to flow from the pump than traditional spray heads. * The face plate inlet can be mounted anywhere above the waterline. * Fits 3/4″ hose. * Includes: Venturi fitting with face plate and 6′ tubing.
