I use a variety of frozen foods that I buy in bulk. About once every 6-8 weeks, I break or chop it into pieces that are approximately the size of frozen cube foods, and put it into approximately 25-30 small (about 1/2 cup sized) tupperware containers and store them in the freezer. That way I have pre-made mixtures of food easily available all the time. One container of food will feed the tank (58 gal mixed reef, heavily stocked with softies, LPS, and sun corals) for 2 or 3 days. I squirt tank water into the container with a baster and keep it in the fridge when not feeding. I use the baster to feed the tank as well, usually aiming it in the general direction of the various sun coral colonies. In addition, I occasionally add some flake food, golden pearls, or pellets to the mix while it thaws. I have been using this method for many years.
