Thanks. I've got several very similar devices already, mostly for minnow buckets and vats, etc.

But I have 2 livewells, one front and one aft. And 3 batteries, all in the very back. And these that run on throwaway batteries are not what I was looking for. Yeah, I could use them and aerate a little bit. They don't do enough in two 23 gallon livewells to matter much, though. I need a 12v system that blows some more air than that. But thanks for looking. It is an option to use on occasion.............
