In-well Aerator Kit is about the easiest way to add oxygen to your live bait well. Use it as your primary aerator, or to recirculate while you’re making a long run across the bay, or if you are trailing the boat, you can stop for fuel and be aerating your catch while the boat is on the trailer. A dependable 500 GPH pump forces water through the aerating head to provide vital oxygen for respiration ensuring your bait stays fresh longer.
