Good job. Thanks for sharing.
I wanted a long(er) term bait tank, so I setup my stock tank with marine metal products 110 air bubbles and a floating aerator with an ammonia filter. So far, so good. Some sort of filter is definitely required if someone is planning to keep hair longer than a couple days. I’ve had great results using quiet bubbles and styrofoam ice chests, but I needed something larger.
I have a couple barrels like you used. Maybe I should set them up like yours. Putting them in the ground would help keep cool
If you can either quickly or quietly switch out shells, you can bring home almost anything.
