Ancient Reef Layers are 100% natural oolite limestone rocks that are cut flat on both sides so that they may be layered on top of one another. Use these unique pieces to create pillars, bridges, and flat ledges for coral placement.
This includes 10 pounds of ancient reef layers, not 10 pieces of rock. Ancient Reef Layers are sold in increments of 10 pounds.
Love Coralline algae? Ancient Reef Layers are also available in our Royal Purple color. Add these to your aquarium for a pop of color.
