CaribSea South Seas Base Rock provides the perfect structural and biological foundation for marine reef aquariums and cichlid tanks. Sustainably sourced, this natural aragonite rock features an incredibly porous, cavernous texture that provides immense surface area for beneficial nitrifying bacteria. The irregular shapes and open contours make it easy to stack stable, natural-looking aquascapes, creating plenty of caves, swim-throughs, and secure placement shelves for your corals. Free from the unwanted pests often found on wild-harvested rock, it provides a clean, safe option for starting a new marine system or expanding an existing reef. This bulk 40 lb box provides an ample supply of assorted shapes and sizes to construct a complete hardscape layout.
Key benefits:
Highly Porous Aragonite Structure: Packed with micro-caverns that maximize surface area for biological filtration and natural waste processing.
Easy-to-Stack Contours: Features natural, rough edges and open crevices that interlock easily, letting you build complex, open aquascapes without collapsing.
Pest-Free Peace of Mind: Naturally clean base rock that prevents problematic hitchhikers like glass anemones, mantis shrimp, or nuisance hair algae from entering your tank.
Excellent Buffering Capacity: Composed of calcium carbonate aragonite, helping naturally stabilize pH and alkalinity levels in marine and high-pH setups.
Specifications:
Net weight: 40 lbs (18.1 kg)
Form: Natural aragonite base rock
Texture: Open, cavernous, and highly porous
Coloration: Natural light tan to earthy cream tones
Water type: Saltwater, Marine Reef, and African Cichlid Aquariums
Intended users: Reef tank hobbyists, marine aquarists, and professional aquascapers
Suggested use:
Aquascaping: Arrange the rock pieces on the bottom of your empty tank (or directly on light grid material) to build a stable foundation before adding sand, preventing burrowing fish from shifting your structures.
Curing/Rinsing: Rinse the rock thoroughly with clean water to clear away any dust from transit before placing it in the aquarium.
Storage and safety:
Store in a clean, dry area if not using immediately.
Handle pieces carefully to avoid breaking delicate, porous shelves or scratching your aquarium glass.
Warnings:
Rinse with clean water before use to clear away any dust from transit.
Keep out of reach of children.
