Activated carbon combats yellow matter and harmful substances
Yellow matter and harmful substances have an adverse effect on the conditions in an aquarium. The water needs to be free of yellow matter if the light is to be allowed to penetrate unfiltered to the corals, plants and fish and bring out their natural colors.
Tropic Marin® CARBON is a highly efficient activated carbon with a powerful capacity for absorbing yellow matter and harmful substances without releasing excessive amounts of phosphate and silicate.
Use and dosage: 400g of Tropic Marin® CARBON are sufficient for 800 l of aquarium water. For continuous use of activated carbon we recommend filtering approximately 1% of the tank volume per hour through Tropic Marin® CARBON. Experience has shown that it is advisable to change Tropic Marin® CARBON after no more then 8 weeks.
Alternatively the carbon can, if necessary (for example after application of medications), be run through a rapid-flow filter over 1 to 3 days.
