These mats are oversized and require additional freight charges. We'll contact you with a shipping quote before your order ships. Alternatively, we can cut the mats in half at no extra freight cost—just let us know when ordering.
High-Density Matala Filter Media for Koi Ponds
Matala filter mats are the gold standard for koi pond filtration, combining mechanical and biological filtration in one proven system. Made from curly fiber Thermo-Polypropylene Compounds (TPPC), these high-density blue sheets deliver superior water clarity and a thriving bacterial ecosystem.
What Makes Matala Different
Unlike standard filter media, Matala's random fiber structure creates micro-turbulence and 3-D water flow. This gentle mixing extends contact time between water and media, allowing beneficial bacteria to colonize more effectively while maintaining the aerobic conditions they need to thrive.
Key Benefits
- High available surface area for robust biofilm development
- Rigid yet flexible design prevents water channeling and dead zones
- Progressive depth filtration increases sludge capacity and reduces clogging
- Easy to cut and customize for any filter design
- Durable, eco-friendly, and long-lasting

Density Options
| Density Grade | Best For |
|---|---|
| Black (Extra Low) | Initial mechanical filtration, pre-filter stage |
| Green (Medium) | Balanced mechanical and biological filtration |
| Blue (High) | Advanced biological filtration, mature systems |

High-Density (FSM365) Specifications
This high-density option provides fine mechanical filtration while maximizing surface area for biological colonization. Ideal for established ponds requiring both clarity and stable water chemistry.
Cleaning Your Filter Media
Rinse gently with pond water using a submersible pump or bucket. Tap lightly on the ground to dislodge debris. Avoid aggressive cleaning—you'll damage the beneficial bacteria that keep your pond healthy. In a well-designed filter, deep cleaning is rarely necessary.
