I got an old Coke round barrel cooler...the kind you see on the floor of convience store with the drinks and the ice in them, it has a drain built in.. I got a air stone from Wal-mart, and a good aerator from Hills Minnow farm...I used an old battery charger...leave it plugged up all the time...to run the air stone and aerator. I also have a cheap filter system from Wal-mart. I use the Better bait stuff that turns the water blue. I keep this in a solid cinderblock building with a cement floor, that was orginally built for a meat house. It stays cool in there. I can keep minnows for several weeks or until it turns really hot. I just go and change most of the water ever couple of days...when I change the water..I have some chlorine remover I got from Wal mart..just a capful cleans the water. My problem is when I leave my house..to go to Tuckertown, I don't pass any stores to get minnows, so I try to have some on hand.
