I run both at the same time in hot water conditions. The bubble system is one I got from Cabela's. It uses two stones like in a fish tank. I can use any of the livewell additives with this setup. I do know with some units that are out there, you cant use rejuvinate. It will kill the fish. Some sort of chemical reaction happens and kills the fish. I turn my pro air on as soon as I throw a fish in the livewell and I leave it on the rest of the day. My fish are jumpin like crazy at the weigh-in and I have never had a fish die in my livewell.
