Filter media bag for aquarium water treatment, sera SERA FILTERMEDIA BAG 2 (mpn 23714)

Sera FILTERMEDIA BAG 2 is a mesh filter media bag designed for organized placement of loose filtration media in aquarium filters. The bag accepts granular and powdered media such as activated carbon, zeolite or biological media, allowing water to flow through while keeping particles and granules contained. Compatible with both internal and external filters, the bag facilitates media handling, reduces mess during maintenance and contributes to clearer aquarium water in freshwater and marine systems.

Advantages

The fine mesh construction prevents leakage of small particles while ensuring sufficient water flow through the contained media. Its flexible shape adapts to different filter compartments and can be securely closed to prevent accidental spills. The bag is reusable, easy to rinse and does not alter the chemical properties of the media placed inside. Designed for aquarium use, it helps keep the filter chamber tidy and simplifies media replacement.

Suitable for

• Holding activated carbon to remove organic contaminants and odors
• Containing zeolite for ammonia and nitrite adsorption
• Packing bio-media to improve biological filtration and surface area
• Use in internal hang-on and external canister filters
• Temporary containment of phosphate-absorbing media or other loose additives

Key specifications

• Material: fine synthetic mesh suitable for aquarium environments
• Closure: secure tie or fastening to prevent spillage
• Compatibility: fits standard filter compartments in internal and external filters
• Reusability: washable and suitable for multiple uses
• Permeability: allows adequate water flow while retaining granules and powders

How to use

Open the bag and fill it with the chosen filter media, avoiding overfilling to ensure proper water circulation. Close the bag securely so that no granules can escape. Place the filled bag into an appropriate compartment of the internal or external filter where incoming water will flow through it. During routine maintenance, remove the bag, rinse it under aquarium water or dechlorinated tap water if necessary, and refill or replace the media according to the media manufacturer's guidance.

Usage recommendations

Rinse new filter media before placing it in the bag to remove dust. Monitor flow rate after installation; if flow is significantly reduced, reduce the amount of media in the bag or clean the bag to restore circulation. Replace chemical absorbents such as activated carbon or phosphate remover according to their specified service life to maintain effective water treatment.
