ADA has released Aqua Soil - Amazonia Ver. 2 Powder Type (3L). This product uses the same materials as the original Amazonia Ver. 2 but with finer grains (due to the limited availability of these finer grains, it is only available in a 3L size). It can be used as substrate for small aquariums or layered thinly on top of the normal type Amazonia Ver. 2 substrate to create a neat and beautiful front line of the substrate. It also makes it easier to plant fine-rooted ground cover plants, reducing the likelihood of them floating after planting. Since it is made from the same natural soil as Amazonia Ver. 2, it promotes water conditions ideal for aquatic plants and tropical fish, making it a user-friendly substrate for both beginners and experts alike. Use it to create a stunning Nature Aquarium.
*Aqua Soil - Amazonia Ver. 2 Powder Type 3L does not come with Amazonia Supplement.
