All carbon is not created equal! It is all black, but that is where the similarity ends. Reef Basis Labyrinth Carbon is a supreme quality, pelletized, steam activated filtration medium particularly selected for sensitive aquarium environments. Labyrinth is bituminous coal based exhibiting huge volumes of mezopores and macropores and suited to adsorption of a wide range of organic pollutants with minimal impact on trace minerals and pH. Labyrinth will remove stains, dissolved organics and toxic gases in marine, brackish and freshwater systems. It has a very high adsorption capability with an iodine number in excess of 1,000 and a molasses number in excess of 600, with immeasurable phosphates and almost no ash content.
Directions and protocol.
Rinse well in cold filtered freshwater, preferably RO or distilled water, but tap water may be used. Place loosely in a polyester filter bag or filter chamber and position to force water flow through the carbon. For best results, use a particulate prefilter ahead of the carbon, such as filter floss or fine sponge. Use about 1 gram of Reef Basis Labyrinth Carbon per gallon of aquarium capacity, or about 3/4 cupful per 100 US gallons (400 L).
