SOIL NERO 1-4mm – Active Substrate for Planted Aquariums and Shrimp Tanks
SOIL NERO 1-4mm is a high-performance active substrate, specially developed for planted aquariums, shrimp tanks, and tropical biotopes. Composed of 100% natural volcanic material, it releases essential minerals, trace elements, humic and fulvic acids, promoting lush plant growth and improving water quality for delicate freshwater species such as Red Crystal and Red Bee shrimp.
Thanks to its pH-stabilizing properties, this substrate maintains the water between pH 6.0 and 6.6, while lowering carbonate hardness (KH 0–2°). It recreates the ideal conditions of natural soft-water environments, suitable for tropical fish and invertebrates from Asia and South America.
The granule size of 1–4 mm ensures excellent root anchorage and nutrient absorption, while its porous structure supports the growth of beneficial bacterial colonies, turning the substrate into a natural biological filter.
Its intense black color enhances the vibrancy of aquatic plants, shrimp, and fish, while giving the aquarium a clean and elegant appearance.
