Activated carbon and zeolite are often used in garden ponds as part of the filtration system. These are mineral and chemically active materials that significantly contribute to water clarity, odor reduction and the removal of harmful substances. Although they are not a biological filter like biofoam or Japanese mat, they supplement filtration and help maintain a healthy ecosystem.
