- 100 % natural black soil
- Helps to lower the hardness level of the water
- High humic and nutrient content
- Nutrient situation even better with the Amazonia supplement
It is perfect for creating an underwater landscape that is very close to the South American rainforest. It offers a high humic and nutrient content and is also suitable for harder tap water.
A high pH value of the soil substrate makes it difficult for aquatic plants to absorb nutrients. Substrates from the Aqua Soil series reduce the hardness of the water and lower the pH to a level where most aquatic plants can absorb the nutrients they need for thriving. The enclosed Amazonia Supplement improves the nutrient situation of the soil even further, so that the plants have particularly excellent growth conditions at their disposal. The Aqua Soil granules retain their shape and density under water for a long time, thus ensuring the circulation of water and oxygen through the substrate.
