Activated carbon to combat 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 adsorbing yellow matter and harmful substances without releasing excessive amounts of phosphate and silicate. After just a short period of use a clear improvement can be seen in the water thanks to the removal of yellowing substances and pollutants. Aquarium inhabitants benefit from the improved amount of light and are restored to their natural colors.

How to use:

400 g of Tropic Marin® CARBON are sufficient for 800 I 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 the carbon after no more than 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.
