Pond filter media is the actual material which allows live bacterias grow, multiple and break down the koi fish waste from building up. Unlike the Pond filters, these are replacements that you can purchase to restore or expand your koi pond. The more fish you have in a koi pond, the more pond filter media you will need. We have a wide selection of pond filter media for you to choose from so call or email us if you need assisstance.
