You do not need to buy frozen foods there. Puree some mussels, oysters, fresh shrimps, fresh fish and some nori and freeze them in ice cube trays. Add some selcon or hufa if you have some and also some cyclopeeze. Thaw a cube or two with some aquarium water and use an eye dropper to target feed your corals at lights out.
Once your inline refugium is going you will be feeding less and less. Migrating Zoo planktons from your refugium will feed your fishes and corals.
