I've started to make my own frozen food as well - it ends up being so much cheaper this way, and I get to control what goes in it. Usually I add Nori, regular shrimp, brine shrimp, vitamins, phytoplankton, and sometimes some high quality pellets or flake food to round it out. If I have extra macro-algae in the refugium I've been know to add that as well. Blend up and place in tiny ice cube trays. My tray has a silicone bottom, so they literally "pop" out of the tray. Couldn't be easier. Fish and corals love it - and instead of adding 3-4 items to the tank at each meal - everything is in the cube.
