HYPERCARBO FAST Decomposing organic compounds release substances that are harmful in the closed system of an aquarium. These substances include pigments, proteins, phenols and lignins. Particulate matter accumulating in the aquarium can act as a constant source of these materials. HYPERCARBO FAST is used to remove both dissolved substances and fine particulate matter, to help keeping the aquarium clean and its inhabitants healthy. HYPERCARBO FAST acts two ways. Ultra-fast absorbing action works by attracting dissolved molecules electrostatically. Mechanical action captures suspended particles in its porous structure.
