High Retention Activated Carbon
Manufactured by Tropical Marine Center
HR Carbon is a highly retentive carbon which is the result of several years development and testing in freshwater and marine aquariums. It is made from carefully selected grades of bituminous coal, ensuring that a consistent quality is maintained.
Recommended for the removal of organics and other toxic substances which gradually build up in marine and freshwater aquariums.
Removes phenols and other organic compounds.
Unlike many cheaper carbons it does not add any phosphates.
Creates crystal clear water allowing better light penetration for maximum plant and coral growth.
Use approximately 1oz per 10 gallons (1g/litre) of system water. Change approximately every three weeks depending on loading. Before use, rinse carbon thoroughly in a fine net to remove any dust created during transportation.
