All rocks are chosen based on color, high porosity and structural integrity. All Marco Rocks undergo a proprietary cleaning process that is free from chemicals, ensuring each piece is ready for use. Marco Rocks is an environmentally conscious and aquarium hobbyist trusted brand!

High-Quality: Foundation Rocks are ultra-porous and support biological filtration. Each rock features a smooth, flat bottom for stability and easy placement. Great for supporting main rockwork in the tank.
