Filter media is the working heart of your pond filtration system. Whether you need mechanical media (foam pads, brushes, mats) to trap solid waste or biological media (bio balls, ceramic rings, moving-bed media) to house beneficial bacteria, Play It Koi carries replacement and upgrade media from Matala, Evolution Aqua, and other top brands.
Selecting Filter Media
For mechanical stages, use graduated density — coarse first, then medium, then fine. Matala filter mats are the industry standard, available in four densities color-coded for easy identification. For biological stages, prioritize surface area — Evolution Aqua K1 and Kaldnes moving-bed media are top choices. Pro tip: never replace all filter media at once. Swap out half at a time to preserve the bacterial colony, waiting at least two weeks between changes.
