Filter sponge insert sera for Fil 60/120 aquarium filters, model SE-06855

sera filter sponge insert for Fil 60/120 aquarium filters (model SE-06855) is a replacement mechanical filtration element designed to fit compatible Fil 60 and Fil 120 filter housings. The sponge traps visible debris and suspended particles as water passes through the filter, helping to maintain water clarity and protect finer biological media located downstream. The insert is intended for routine maintenance and periodic sponge replacement to support consistent filter performance in both freshwater and marine aquaria.

Advantages

The sponge insert offers effective mechanical filtration with a porous structure that captures detritus without restricting normal flow through the filter unit. As a purpose-made spare part for Fil 60/120 housings, it ensures dimensional compatibility and straightforward replacement. Using a dedicated sponge insert reduces load on other filter stages and helps prolong the life and function of biological media by preventing premature clogging.

Suitable for

• Routine maintenance and sponge replacement in Fil 60 aquarium filters
• Routine maintenance and sponge replacement in Fil 120 aquarium filters
• Mechanical pre-filtration to protect biological media in freshwater aquaria
• Mechanical pre-filtration to protect biological media in marine and reef aquaria

Key specifications

• Function: mechanical filtration (sponge media)
• Compatibility: designed for Fil 60 and Fil 120 filter housings
• Material: porous synthetic foam suitable for aquarium use
• Application environment: suitable for freshwater and marine aquaria
• Purpose: replacement service part for routine maintenance

How to use

Turn off the filter and follow the manufacturer's instructions to access the filter chamber. Remove the old sponge insert and inspect the filter housing and other media for debris or wear. Rinse the new sponge briefly in aquarium water to remove loose particles, then place it into the filter chamber in the same orientation as the original. Reassemble the filter, restore power, and monitor flow and water clarity to confirm correct installation.

Usage recommendations

Replace the sponge insert at regular intervals based on bioload and observed clogging; inspect during routine maintenance and clean or replace sooner if flow decreases or the sponge is heavily soiled. When cleaning, rinse the sponge gently in water taken from the aquarium to preserve beneficial bacteria on adjacent biological media. Do not use detergents or hot water.
