Polyp Lab, the maker of Reef Roids was kind enough to sponsor this video. Reef Roids is one of the most popular powdered plankton foods on the market and in this video we test it out on several of our corals here at the Tidal Gardens coral farm to see which ones eat it and which ones don't. As an added benefit, Tidal Gardens' customers will receive a free sample of Reef Roids to try on their home aquariums.
