I recently fished a tournament on Sam Rayburn and lost first place due to a dead fish. I know that sometimes there is nothing more you can do to keep one alive, but I want to maximize my livewell systems. I know about cooling the water temps down. I am looking for more of a product suggestion. I am looking into the Oxygenator by TH marine and also the vents for the lids of the livewells. What GPH would yall recommend for an Aerator/Live well pump? Any other product suggestions? Thanks for all the comments.
