I use a regular styrofoam minnow bucket and set it down inside of a 5 gallon bucket. I hang my aerator on the side and run an air tube with a stone through the top of the styrofoam lid, and i hang a cloth bag with extra batteries on the otherside of the aeroator for balance. Works great. I also have an electric aerator for an aquarium I use so I can buy minnows the night before or keep leftovers for the next trip, just plug it in a let it run all night
