Aqua Natural Ebony Pearl Premium River Gravel Substrate 4.5kg

Give your aquarium, terrarium, or biotope setup an exquisite, high-end aesthetic with Aqua Natural Ebony Pearl Premium River Gravel. Recognized as the deepest natural river stone available, Ebony Pearl is sustainably harvested from the pristine, water-tumbled environments of Southland, New Zealand. These unique stones possess a beautifully smooth, rounded-to-oval profile that transforms into a brilliant, glossy jet-black color when submerged, instantly creating a striking contrast that intensifies the natural colors of fish, dwarf shrimp, and vibrant green aquatic plants.

Engineered to meet the exact demands of modern aquascaping and ecosystem health, this premium river gravel is 100% natural and completely water-inert. It will not leach minerals, shift your pH, or affect carbon hardness (GH/KH), providing a perfectly stable foundation for sensitive freshwater communities, high-tech planted tanks, and delicate shrimp colonies alike. The carefully screened 2–4mm sizing promotes exceptional root anchoring while allowing optimal water circulation through the substrate bed to prevent hazardous anaerobic stagnation.

Key Features

• True Natural Deep Black: Sourced from New Zealand river beds to deliver a genuine jet-black look when wet without using any artificial pigments, dyes, or chemical coatings.
• 100% Inert & Water Safe: Will not alter delicate aquarium water parameters, affect pH, or buffer hardness, ensuring maximum safety for all aquatic life.
• Fish & Invertebrate Friendly: Ultra-smooth, water-tumbled texture prevents structural injuries or scratches on sensitive bottom-dwellers such as Corydoras, loaches, and shrimp.
• Optimal Root & Biological Base: The 2–4mm micro-pebble sizing offers excellent anchoring stability for live plants while promoting essential nitrifying bacteria growth.
