Master Soil Black Powder - 3L

Master Soil Black Powder 3L is a premium Japanese-manufactured active substrate made for freshwater planted aquariums, shrimp tanks, and tropical fish setups that benefit from a nutrient-rich base. The fine powder-style grain is especially useful for carpeting plants and detailed aquascapes, while the rich black colour gives plants, shrimp, and fish strong visual contrast.

This type of active soil is designed to support healthy root feeding and a more stable planted-tank environment when used correctly. It is a practical choice for nano tanks, aquascaping layouts, shrimp-focused aquariums, and display tanks where both plant performance and a neat natural finish matter.

Key Features

• Grain Size: Fine powder grain that spreads evenly and helps anchor delicate roots, especially useful for foreground and carpeting plants.
• Colour: Deep black substrate that enhances the colours of green plants, red plants, shrimp, and small tropical fish.
• pH Effect: Active soil may help create a planted-tank-friendly environment and is commonly preferred in setups that aim for slightly softer, mildly acidic water conditions.
• Suitable For: Freshwater planted aquariums, aquascapes, shrimp tanks, nano tanks, and tropical community aquariums with rooted plants.
• Nutrient Support: Designed as an active nutrient substrate to support root-feeding plants and improve early plant establishment.
• Aquascaping Use: Fine texture makes it ideal for smooth slopes, foreground detailing, and compact layouts where a refined substrate look is preferred.
• Tank Compatibility: Best suited for freshwater use; commonly chosen for planted and shrimp-focused aquariums rather than rough digging fish setups.
• Pack Size: 3 litre pack, suitable for nano tanks, small planted layouts, or as part of a layered substrate plan.

How To Use

• Preparation: Do not wash active soil aggressively, as this can break the granules and reduce the intended performance of the substrate.
• Depth Recommendation: Use roughly 3 to 5 cm for simple planted tanks and 5 to 8 cm where stronger root development or aquascape contouring is needed.
• Layering: Can be used on its own or combined thoughtfully with base additives depending on plant demand and the age of the setup.
• Planting Tips: Insert rooted plants gently with tweezers to avoid disturbing the fine powder texture; ideal for Monte Carlo, hairgrass, and other foreground species.
• Water Filling: Fill the aquarium slowly over a plate, plastic sheet, or bag to reduce clouding and keep the aquascape shape intact.
• Initial Maintenance: In newly set planted tanks, regular water changes during the first few weeks are recommended as active soils can release nutrients in the early stage.
• Filter Support: Good biological filtration and stable cycling are important, especially in shrimp tanks and high-value aquascapes.
• Best Use Case: Excellent for aquarists who want a clean black foreground, better plant rooting, and a substrate tailored for planted freshwater systems.

Master Soil Black Powder 3L is a strong option for aquascapers who want a refined grain, attractive black finish, and a substrate that suits rooted plants and shrimp-friendly freshwater layouts. For best results, pair it with appropriate lighting, regular maintenance, and a planting plan that matches the nutrient demand of your aquarium.
