MarcoRocks STAX Flat Stacking Aquarium Rock – 18 kg

MarcoRocks STAX is flat, porous oolitic limestone cut on both sides so the pieces stack easily. It is 100% natural, sustainably collected and free of chemicals or additives, and it suits marine or freshwater aquariums. Used with aquarium mortar, STAX lets you build open, gravity-defying structures with plenty of horizontal surface for placing live corals, and the average 3–5 inch pieces, about an inch thick, are perfect for nano aquascapes or extending an existing rockwork.
