A tough curly-fiber matrix that does mechanical and biological filtration in one — open densities trap heavy solids, fine densities polish the water and host beneficial bacteria. Cut to fit any filter. In stock — ships from Southern California92-94% free volumeMechanical + biological in oneAuthorized Matala retailer Progressive filtration Run coarse-to-fine so solids are trapped up front and finer layers polish without clogging. Huge surface area The 3D web holds enormous biofilm area and, per Matala, ~10x its weight in sludge before clogging. Easy to clean Shake or rinse with pond water — no pressure. Cleans in seconds without killing your bacteria. Cut to fit Holds its shape; cut with a knife or saw to fit any tank, sieve or chamber. The four densities Color Density Surface* Best for Black (FSM190) Super coarse ~190 m²/m³ Heavy solids, stage 1 Green (FSM290) Coarse ~290 m²/m³ Solids + bacteria Blue (FSM365) Fine ~365 m²/m³ Polish + bacteria Gray (FSM460) Super fine ~460 m²/m³ Final polish *Specific surface area, manufacturer spec (Matala). Sheets sold in quarter, half and full sizes. How much do you need? A simple rule of thumb: roughly 1-4 full sheets per 1,000 gallons by fish load — 1 for a light water garden, 2-3 for ornamental ponds, 4+ for heavily stocked koi. The heavier the load, the more media. Build progressively: stack Black → Green → Blue → Gray in the direction of flow so each layer does its job. Try the live sizing helper on the Matala hub.
