I jut got done installing a Power bubbles air pump and lines in my livewells. I was looking and it has a single 1/4" thick fiberglass board separating the two boxes. I thought about taking a hole saw and drilling a half a dozen holes in it to improve water flow between the boxes. I like the seperation there so I can put an unhealthy fish alone and let her relax. Would there be any advantage to doing this or more importantly disadvantage to doing this?? Thanks!

I would think you would want the best flow possible. If it really is just a piece of fiberglass separating it I would probably put some 1" holes in it. But both of my livewells are open so I have no experience with a sectioned livewell.
