I use something similar, but I put slicks in mine, no minners here (most times)

Instead of an aquarium pump, I use a bilge pump connected to a piece of hose that is connected to a livewell spray nozzle in the cooler, it moves ALOT of water, and sprays the water enough to keep 80 3" slicks alove of r 2-3 days. Just hook it up to your battery in your boat. All pieces available at Wally-World or Academy for under $25
