07. Applying a Suitable Substrate

Bottom of the aquarium should be filled with a layer of laterite and cover the laterite with aquarium gravel such as pea gravel or the other substrate with rich in minerals designed for plants. In this case, the thickness of the bottom layer should be 5-8 cm. Generally, 1.5 pounds of gravel is needed per gallon of water. Gravels should be different sizes which provide support for the plant roots.
