It's just me, so I only need one running at a time. Every day I take one serving out and put another one in. I clean the tank about once per week, or if something breaks. My favorite is short ribs, my daily drivers are chuck roast or shank. The prices have skyrocketed in the last few years. I buy in bulk on sale and portion it into bags with a chamber style vacuum sealer. It goes straight from the freezer into the tank.
