Rod`s Food have many years of experience and learning that has made their blending process unique. Rod`s Food is made by hand in our U.S. facility, not machine processed overseas. They use whole animals, not just tails that are available at any local grocery store. Using the whole animal provides the most nutrition. No unnecessary gels or food binders are added to Rod`s Food. And their foods are not water packed! Most users are amazed by how a small amount of Rod`s Food can feed an entire reef. A little goes a long way!
