? Activated Carbon - Granules of Carbon Filter Media. Ideal for use in fish tanks, ponds, internal filters, external filters, sumps and aquariums.
? This form of activated charcoal is manufactured as small stones that have a higher surface area to volume capacity compared to other forms such as pellets.
? The stones are an ideal filtration size and will not clog or significantly impede flow.
? What is Activated Charcoal? Activated Carbon is a form of carbon that has very high porosity, which makes it an ideal filtration media. Carbon is also good at binding to most substances, this means that when fluids such as water are passed across it, it acts to filter out pollutants and contaminants. The surface area of one gram of granular activated charcoal typically ranges between between 1,300 to 2,900 metres squared.
? How do I use Activated Charcoal? Activated Carbon is frequently used to filter water for example for ponds and aquariums. Usually, the charcoal is used in a mesh bag that can be wholly submerged with a continuous flow of water from a pump. Repeated filtration reduces the level of impurities over time and acts to purify the water. This product is ideal for use in both internal and external filter bags and can be used for salt and fresh water applications.
