The Flagship design for REEFROCK is the HONEYCOMB. It incorporates the qualities of a flat style Live Rock along with holes that increases water circulation and crannies that creates water motion reducing "dead zones" in your aquarium.     All of us that design Reef Systems search for this type of Live Rock whenever we go to our local supplier. To have this look always available allows aquascaper's quick design results. It can be used vertically or horizontally or broken into that perfect size to fit your tank's ideal layout.     As with all of our REEFROCK products, the rock's colors will vary from our Coral Pink to our Deep Purple. And since all pieces are cured in the oceans around the Islands of Fiji, they develop their own coralline algae, as well as, other normal growths.
