Sera Filter Bag 25x15cm

The Sera Filter Bag 25×15 cm is a durable, reusable mesh bag designed to simplify aquarium or pond filtration maintenance. It helps contain loose filter media (such as activated carbon, bio-rings, siporax or filter wool) so that media stay neatly in place and can be removed or replaced quickly — no messy spills or lost granules. Compatible with both freshwater and marine setups, the bag makes cleaning or swapping media simple and fast, and helps ensure effective filtration by keeping media consolidated and evenly exposed to water flow.
