This is my tournament catfishing livewell I made out of a tractor supply storage box I got used from a friend, the box is steel so it's not ideal but for now it will work. All pvc fitting where sourced from the local Woodson's and the pump and float from Marineland in Waco. the oxygen bottle come from Matheson in Mexia. Ive got about 275 in the set up but the bottle alone was around 165$ I think and the box was 50$. I think with the oxygen injection it is going to keep the fish nice and healthy!!
