Advanced Coral Tissue Supplement for all Corals & Their Allies Overview Encourages health, growth, reproduction, and vibrant coloration. Provides important nutrients to corals and their allies during periods of stress induced by changes in lighting and/or prolonged exposure to excessive water temperature (often resulting in “bleaching”). Aids in tissue repair after corals have undergone fragmenting and captive propagation. Does not require refrigeration. Formulated by a marine scientist.
