Bioscape Carbon Extraction Pad 25 x 45cm
One sheet, cut to fit whatever filter you own. The Bioscape Carbon Extraction Pad is a 25 × 45 cm carbon-impregnated poly-fibre sheet you trim to size, for power filters, trickle filters, wet/dry filters, powerheads, canister filters and pond filters alike.
Key features
- One size fits any filter – cut a strip or panel to match your filter's media chamber instead of hunting for a brand-specific cartridge.
- 25 × 45 cm sheet – enough for several cuts on most household filters.
- Removes tannins, odour and discolouration – activated carbon adsorbs dissolved organics, chlorine, phenols and residual medication.
- Freshwater and marine safe.

Will it fit my filter?
Because it's a cut-to-size sheet rather than a shaped cartridge, it fits almost any filter with an open media compartment – trim it to the chamber size with scissors. It won't help on a filter that only accepts a sealed, brand-specific cartridge with no room to fit trimmed media.
Care and maintenance
As a general guide, replace the cut section roughly every 4 weeks of continuous use – activated carbon has a limited adsorption life and stops improving water clarity once exhausted, though it's not harmful left in place. Rinse a fresh-cut piece before fitting to clear loose carbon dust.
Suitable for, and not suitable for
- Suitable for: any filter with an open media tray or bag – freshwater or marine, including ponds.
- Not suitable for: filters that only take a sealed, pre-shaped cartridge.

Common questions
How do I size a piece for my filter?
Lay your old cartridge or media chamber on the sheet and cut around it with scissors, leaving a small margin so it sits snugly.
How long does one sheet last?
Depends on your filter's chamber size – most household filters get several cuts from one sheet before it's used up.
Is it safe for shrimp and plants?
Yes, plain activated carbon media doesn't affect invertebrates or live plants.
