Important Shipping Information These Matala 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. Low Density Biological Filtration Media Matala filter media represents the latest generation of filtration technology for koi ponds and aquaculture systems. Made from curly fiber Thermo-Polypropylene Compounds (TPPC), these mats deliver both mechanical and biological filtration in a single, versatile solution. Why Choose Matala? Rigid yet flexible design maintains proper water flow and prevents channeling Exceptionally high surface area supports robust biofilm development Random fiber structure creates micro-turbulence for longer water contact time Easy to cut and customize for your specific filter configuration Durable, eco-friendly, and long-lasting How It Works The layered fiber structure creates interstitial spaces where beneficial bacteria colonize. As water passes through, gentle mixing and turbulent flow maximize contact time between water and biofilm, dramatically improving filtration efficiency. This allows you to use smaller or fewer filter tanks while maintaining superior water quality.

Avoid aggressive cleaning—your filter media hosts essential bacteria that keep your pond ecosystem balanced. Light rinsing removes excess debris while preserving the beneficial biofilm.
