Macroalgae For Marine Reef Aquariums: Refugium Macroalgae Pack ecosystems

Live Sand  

Our live sand is a natural product collected from both the Gulf of Mexico and Atlantic. The substrate is a mixture of aragonite, coralline encrusted rubble and shells. We use this sand as our primary source of filtration in all of our macro algae systems and it provides an excellent natural substrate for larger burrowing invertebrates.
