Foam filter accessory sera 8460 for aquariums — foam cartridge, 1 pc, made in Germany

sera foam filter accessory 8460 is a replacement foam cartridge designed for mechanical prefiltration in home aquariums. Supplied as a single piece, the foam cartridge is made in Germany and fits compatible sera filter units. It captures fine dirt particles and suspended debris, helping to maintain water clarity and protect downstream biological filter media.

Advantages

The foam cartridge is made from stable fibers that retain finer dirt particles for an extended period without collapsing or sticking together; it can be washed and reused several times to extend service life. As a dedicated mechanical filter insert, it supports consistent water flow and reduces the load on biological media when used as part of a complete filtration system.

Suitable for

• Regular mechanical prefiltration in home aquariums
• Replacement foam cartridge for compatible sera filter units
• Protecting biological filter media from clogging by coarse and fine debris

Key specifications

• Function: mechanical prefiltration (foam cartridge)
• Quantity: 1 piece per package
• Material: stable synthetic foam fibers designed for repeated washing
• Compatibility: fits compatible sera filter housings and units
• Origin: made in Germany

How to use

Rinse the foam cartridge under warm tap water before first use to remove any packaging residues or loose particles. Insert the foam cartridge into the designated slot or chamber of the compatible sera filter unit ensuring correct orientation and secure seating. Perform routine maintenance by removing and rinsing the foam under warm water when visibly dirty or when flow rate decreases; allow the foam to drain briefly before reinserting. Replace the cartridge when it no longer restores adequate flow or shows signs of permanent deformation.

Usage recommendations

For best overall filtration, combine the foam cartridge with a biological medium such as sera siporax Professional and, if required, a chemical adsorbent like sera phosvec･clear. Use the foam as the first mechanical stage to trap particles, which makes subsequent removal of bound substances easier and reduces clogging of biological media.
