Master Soil is a premium Japanese aquarium substrate that naturally regulates water parameters by reducing pH, GH, and KH levels. It is rich in plant nutrients like fulvic and humic acids, as well as essential minerals, and contains a higher nutrient concentration than comparable substrates like Platinum Soil. Master Soil is suitable for planted tanks, as well as for breeding ornamental bee shrimp and tropical fish, and is designed to support healthy aquatic environments.
About Master Soil
Produced in Japan from natural soil, Master Soil offers exceptional absorption properties and high porosity. Its structure prevents anaerobic zones and promotes rapid bacterial colonization, which helps quickly decompose ammonia (NH4+) and nitrite (NO2). This results in extended intervals between water changes and a more stable aquarium ecosystem.
