Activated Carbon Stands so they are not typicallyA superior, high purity, bituminous coal based activated carbon designed for water purification. Preferred by public aquariums, research centers and government fisheries. The small particle size (approximately 1 16 to 1 8) provides a large surface area for rapid uptake and reduces water travel distances to interior adsorption surfaces. Keeps water crystal clear. Absorbs full range of organic contaminants, pesticides, odors, colours, chlorine,
