## Summary description

Coarse-grain aquarium filter sponge by HAPPET sized 50 x 50 x 5 mm. Designed for mechanical filtration to trap larger debris and protect biological media in aquarium filter systems. Suitable for use in small internal filters, hang-on or canister pre-filters and custom filtration setups. Easy to cut to shape and rinse for reuse.

## Long description

Coarse-grain filter sponge HAPPET 50 x 50 x 5 mm is a mechanical filtration insert designed to capture larger debris in aquarium systems. The flat, open-cell foam traps uneaten food, plant fragments and suspended particles before water reaches finer biological media. The compact dimensions make it suitable for small internal filters, hang-on pre-filters, canister pre-filtration chambers and custom DIY filtration setups. The sponge is washable and can be trimmed to fit non-standard filter housings.
Advantages
This coarse-grain sponge provides effective mechanical filtration of large particles while protecting downstream biological media from clogging. Its open-cell structure allows good water flow and reduces resistance in low-power filters. The thin 5 mm profile fits tight spaces and is easy to cut with scissors for a precise fit. It can be rinsed and reused multiple times, offering a practical, low-maintenance pre-filter solution for small aquaria.
Suitable for
 Small internal aquarium filters
 Hang-on filter pre-filters
 Canister filter pre-filtration chambers
 Custom or DIY filtration setups
Key specifications
 Material: coarse open-cell foam for mechanical filtration
 Dimensions: 50 x 50 x 5 mm
 Thickness profile: thin 5 mm sheet suitable for shallow filter slots
 Function: captures larger debris and protects biological media
 Maintenance: washable and reusable
How to use
Rinse the sponge under aquarium-safe water before first use to remove any loose particles from manufacturing. Insert the sponge into the filter chamber or place it as a pre-filter in the flow path so water passes through the foam first. Trim to size with scissors if necessary to achieve a snug fit and avoid blocking flow. Inspect the sponge during routine maintenance and rinse gently to remove trapped debris; replace when the foam shows signs of permanent compression or deterioration.
Usage recommendations
For optimal performance use this coarse-grain sponge as the first stage in a multi-stage filtration setup: mechanical pre-filtration with this sponge followed by finer mechanical or biological media. Rinse periodically rather than washing with detergents; avoid exposure to strong chemicals and hot water. Monitor flow rate after installation—if flow is significantly reduced, clean the sponge or use a thinner placement to maintain adequate circulation.
