Master Soil Next HG Black Powder 8L – Japanese Planted Aquarium Substrate

Master Soil Next HG Black Powder is a premium active substrate from Japan, specially formulated for planted aquariums and ornamental shrimp tanks. Designed to enrich aquatic environments, this substrate releases essential plant nutrients—including fulvic and humic acids—while naturally stabilizing water parameters such as pH, GH, and KH for a healthy aquatic ecosystem.

Why Choose Master Soil Next HG?

• Rich in nutrients: Packed with minerals and acids essential for lush aquatic plant growth.

• Water quality regulation: Lowers and stabilizes pH, GH, and KH levels to ideal ranges.

• Superior porosity: Multi-stage surface sintering creates a highly porous substrate, preventing anaerobic zones and promoting beneficial bacteria colonization.

• Long-lasting: Designed for prolonged use, reducing the frequency of water changes.

• Ideal for shrimp & fish: Supports breeding of ornamental shrimp and tropical freshwater fish.

• Quick water clarification: Rapidly clears tannins released from driftwood or roots.

Usage Guidelines

• Recommended substrate volume: 24–32 liters for 120–150 liter aquariums.

• Fill the tank with substrate without rinsing. Add water gently to avoid disturbing the soil.

• Initial cloudiness is normal and will clear within hours with filtration.

• Remove any surface film by partial water changes.

• Brownish stains on glass can be wiped off and do not affect water quality.

Important Notes & Precautions

• Use only in freshwater planted or shrimp aquariums.

• Do not mix with other substrate types; use Master Soil alone for best results.

• Avoid additional pH or KH-lowering chemicals to maintain stable water chemistry.

• Not a treatment for fish or plant diseases.

• Store sealed and use promptly after opening to prevent drying and brittleness.

• Always monitor water parameters, especially for sensitive species.

• Keep out of reach of children—packaging poses suffocation risk.

• Powder Type: 2.5mm – 3mm
