Ive been using akwa-lung for a couple yrs. now and just had a new live-well made for my boat. after looking at everything i changed for few things and it made a big diff. in the way it works. i used bigger fittings, and i drilled a bigger hole in the oxygen infuser tapped it , put a fitting on that and run a 5/16 hose out side the tank. i can fill the tank all the way with the infuser under water and it works better than ever. i took pics. of it so you can see just how i did it, and what kind of flow it has now. i turned the the unit so you can see how far the flow goes across the tank. its just one a great product. i had ten fish in the tank sunday all were 12 to 20 pounds, it was very hot and the water out of the ole miss was as muddy as Ive ever seen it, the fish did just fine.
