MarcoRocks Nano Shelf – Coralline Edition

The Ultimate Foundation for Your Nano Reef

Build a professional-grade aquascape in even the smallest footprints with MarcoRocks Nano Shelf. This specific cut of rock is highly sought after for its flat, plate-like geometry, allowing you to create dramatic overhangs, terraced ledges, and ample real estate for coral placement without the bulk of traditional boulders.

Product Highlights:

• Instant Reef Aesthetics: Featuring the proprietary MarcoRocks "Coralline" finish, this rock mimics the deep purple hue of mature coralline algae right out of the bag. You get the look of a seasoned tank on day one, without the wait or the chemical instability of painted rocks.

• Perfect "Shelf" Geometry: Unlike standard rounded rocks, these pieces are hand-selected flat slabs. They are the ideal building blocks for creating caves, shadowing for low-light corals, and multi-level platforms that maximize swimming space in nano and pico aquariums.

• 100% Pest-Free Guarantee: Sourced from ancient, dry coral reefs on land, MarcoRocks are guaranteed free of nuisance algae, Aiptasia, parasitic isopods, and Mantis shrimp. You start with a clean slate every time.

• Environmentally Sustainable: Harvested responsibly from ancient reef structures in Florida, this product requires no destruction of living coral reefs, making it the ethical choice for the modern reefer.

Why Choose MarcoRocks Nano Shelf?

• Massive Porosity: Despite being sedimentary rock, the natural calcium carbonate structure is intensely porous, acting as a powerful biological filter housing millions of beneficial bacteria.

• Chemically Neutral: The rock is calcium carbonate based and will naturally buffer your pH. The purple finish is chemically stable and safe for all marine life.

• Ready to Build: Completely dry and clean. No curing, "cooking," or extensive cycling required to remove die-off. Simply rinse and build.

Aquascaping Pro-Tip:

Create Gravity-Defying Structures: Because MarcoRocks Nano Shelf is dry, you can take your time designing your hardscape outside the tank.

• For Stacking: The flat surfaces stack naturally, but for a permanent bond, use E-Marco-400 mortar.

• For Instant Hold: Use the "Sandwich Method" with cyanoacrylate (super glue) gel and stone powder to lock shelves together instantly, allowing you to create complex cantilevered ledges.
