Aqua Soil Amazonia has been used by many planted aquarium hobbyists around the world, as base substrate material for growing aquatic plants. Aqua Soil Amazonia is produced from black soil with rich organic substances, helping the plant growth, and most aquatic plant species can grow in healthy condition with Amazonia. But, in the alkaline base water*, there are rare case reports that organic substance such as humic acid may seep into the water, and cause water coloring or cloudiness. So this time Aqua Design Amano introduced "Aqua Soil-Amazonia II", a new Amazonia type substrate, produced with different black soil mixture ratio, preventing water coloring or cloudiness. As the base color or plant growing pattern is slightly different from original Amazonia. Please select them according to your needs and preference. But if your base water* is alkaline, we recommend to use Amazonia II.
