So I have had my ato set up for about a month now. The tank is in the dining room and there is no room under the tank for a container. Right now it feeds off if a white 5 gallon container on the side of the tank. I dont mind the white but I'm looking for something larger that fits in the same area so I don't have to keep swapping out containers every week or so. I'm looking for inexpensive ways that fit the area. Anyone have any thoughts? Not really sure what out there is food safe or ok to use or what not. The footprint is 16" x 15". TIA for any thoughts. Mike
