ADA Power Sand Basic is a base substrate material designed for providing nutrients to the roots of aquatic plants and promoting growth of substrate bacteria. Porous volcanic stones ensure the water circulation, and organic nutrients promote the growths of bacteria. Please select right amount according to the depth of aquarium tank. When only one kind of granule is used in the substrate it does not provide enough water circulation down to the bottom of the aquarium, so in a short time waste matters from plants and plant roots block the space between granules and obstruct the water circulation. The mixed substrate with ADA Power Sand at the bottom secures good water circulation due to the shape and size of the granules. Even when aquatic plants have been growing for long periods and waste matter accumulates, ADA Power Sand is composed of porous volcanic stones to maintain proper water circulation. The growth of aqua plants like Echinodorus or Cryptocoryne, plants that absorb nutrients from its root, largely depends upon the amount of nutrients within the substrate.
