I made mine like a boat live well. I took some air line, blocked off the end, drilled several hole in it, and stuck it on the pump. I may make another line with fewer holes in it. No filter,, didn't think about that. I guess I have to think of adding one. I'm thinking with the water moving as quickly as it is, it shouldn't freeze up. I'll move it into the bulkhead tomarow, and see what it does over night.
