MarcoRocks MR Foundation Rock - 20lb Box Natural

The MarcoRocks Natural Foundation Rock (20lb Box) is an all-natural calcium carbonate rock designed specifically for the bottom layer of marine aquarium aquascapes. Mined from ancient, extinct reef systems, this eco-friendly rock ensures a stable, pest-free foundation for your aquarium. Each 20lb box typically contains 6-10 pieces, with each rock weighing 3-5 pounds, providing the perfect solution for creating a solid base layer that prevents "rock slides." The machined flat bottom ensures stability against the glass, while the natural-shaped top offers an organic, natural look for your aquarium.

Key Features:

• Stable Design: Features a machined flat bottom for added stability against the aquarium glass and a naturally shaped top for an organic appearance.
• Pest-Free Guarantee: 100% free of nuisance algae, Aiptasia, and parasitic isopods, as the rock is harvested from ancient land-based reef formations.
