The soil is collected at the foot of the Aso mountain range, a famous active volcano in Japan. Fluval soil stimulates the growth of plants in a freshwater aquarium, because the roots of the plant grow in a substrate that contains everything necessary for growth and development. The soil contains all the necessary macro and micro elements. The light porous structure is an ideal place for nitrifying bacteria, which quickly colonize the porous surface and ensure an optimal water balance for plants. Fluval helps maintain a neutral or slightly acidic pH, ideal for most plants and tropical fish and shrimp.
