Power Sand is the base of the Nature Aquarium substrate. Power Sand is composed of porous volcanic stones to secure proper water circulation and of organic materials including fertile peat to provide rich nutrients to aquatic plant roots. Ideal conditions for bacterial activity and development of plant roots are created and maintained for long periods with Power Sand.
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. Unlike ordinary Power Sand, Power Sand Special provides more minerals and nutrients to the substrate, as it also contains Bacter 100 and Clear Super.
WATER CIRCULATION IN THE SUBSTRATE WITH POWER SAND
Water circulation. A new substrate has a good circulation of water which carries oxygen to stimulate bacterial activity and the development of plant roots. This is the ideal condition of substrate, in order to establish a balanced ecosystem. After some time, however, various factors may cause problems in the substrate.
Although problems would not appear at early stages, a substrate with only one kind of granule does not provide enough water circulation down to the bottom In a short time. Waste matters from plants and plant roots block the space between granules and obstruct the water circulation.
Water pressure. Some time after setup, water pressure or calcium in the water hardens the substrate. At this time, water circulation within the substrate is obstructed and bacterial activity declines. Such a condition causes problems in root development and growth of aquatic plants. The mixed substrate with 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, Power Sand composed of porous volcanic stones maintains proper water circulation.
RELATIONSHIP BETWEEN PLANT ROOTS AND BACTERIA WITHIN THE SUBSTRATE
Silt gathers around plant roots and provides a good medium for bacterial colonization. Proper functions of bacteria, through their nitrifying processes, change ammonia to nitrogen compounds which are then consumed by aquatic plants through their roots.
Oxygen- Sufficient supply of oxygen is vital for aerobic bacteria. Insufficient oxygen prompts the activity of anaerobic bacteria which produce toxic substances such as nitrous acid.
Nutrients in Power Sand- Nutrients contained in Power Sand are slowly dissolved and absorbed by plant roots.
Fertilizer in the substrate- Organic matter in Power Sand or other bottom fertilizers such as Multi Bottom or Iron Bottom, can be absorbed by aquatic plants, only when they are broken down to inorganic matter by bacteria.
Fertile peat- Works effectively to stimulate the establishment of association between bacteria and aquatic plants.
Use Power Sand Special "M" (medium size granule) for aquariums from 16 in. (40cm) to 24 in. (60cm) heights.
This hardness is free shrimp gravel water neutral, light and CO2 resistant. It is used fish-keeping. The gravel is rounded and has a grain size of 0.7 to 1.2 mm.
Pollutant-free shrimp gravel with rounded grains for a minimal risk of injury. Does not change the water values due to its water-neutral and CO2 resistant texture.
Aquarium gravel ideal for shrimp tank and other aquariums. It is used for fish-keeping. This is safe for shrimps and crabs. It is CO2-proof and water neutral. Available in yellow colour.
