Soil contains plentiful nutrients, which makes it excellent for planted aquariums. Additionally, it is an active substrate that brings down the carbonate hardness (KH) and maintains a stable pH level. Many aquatic creatures as well as plants favor soft, slightly acidic water, resembling their tropical habitats. Composed entirely of valuable clay minerals, Soil is a natural product. With a porous 2-3mm grain size, filter bacteria possess a prime colonisation area, elevating biological filtration. Out of the bag, Soil substrate is ready to use without the need for an extra layer of gravel.
