Bacteria House filter media, originally developed by Mr. Michio Maeda is a ceramic product that provides an ideal environment for raising koi fish. Japan is world-renowned for the beauty of its koi and with this innovation, you can bring their natural surroundings to your home. Momotaro Koi Farm was established by Mr. Maeda. Over six years of research resulted in Bacteria House filter media which is designed to replicate the conditions of the Ashi River and Bakuanseki Spring, two familiar locations popular with avid fisherman and koi keepers alike!
