Aqua Clay Balls 2 mm for Aquarium Gravel Substrate 500 grams Packet

Build a thriving, nutrient-rich foundation for your planted aquascape with Aqua Clay Balls, available at www.onyxaqua.com. These highly porous, 2mm baked clay spheres provide an ideal, breathable rooting environment for aquatic plants while simultaneously acting as an exceptional biological filter media for your entire tank.

Key Features & Benefits

• High Cation Exchange Capacity (CEC): Naturally absorbs excess nutrients and liquid fertilizers from the water column, storing them safely and slowly releasing them directly to plant roots for robust, sustained growth.

• Massive Biological Surface Area: The microscopic internal honeycomb structure hosts enormous colonies of beneficial nitrifying bacteria, ensuring a stable nitrogen cycle and crystal-clear water.

• Zero Substrate Compaction: The uniform 2mm spherical shape guarantees optimal oxygen exchange and continuous water flow through the substrate bed, permanently preventing the buildup of toxic anaerobic gas pockets.

• Safe for Bottom Dwellers: Unlike jagged gravel, the perfectly smooth, rounded edges of these clay balls make them incredibly safe for delicate bottom-foraging fish like Corydoras and sensitive dwarf shrimp.

• Unrestricted Rooting: The lightweight nature and ideal 2mm size allow delicate aquatic plant roots to easily navigate, anchor securely, and spread throughout the substrate without encountering heavy resistance.

• Natural Aesthetics: The rich, earthy brown terracotta coloring provides a stunning, high-contrast natural base that makes the vibrant greens and deep reds of your aquatic plants truly stand out.

Technical Specifications

To get the most out of your new substrate, give the clay balls a gentle rinse in a sieve before adding them to your aquarium to wash away any fine dust accumulated during shipping. Because they are highly porous baked clay, some balls might initially float upon contact with water; simply let them soak for a short period until they become fully waterlogged and sink to form your beautiful underwater landscape.
