This black sponge pad is a replacement pre-filter for Jingeye hang-on aquarium filters, cut to 106×64×9.6mm. It traps larger debris — uneaten food, flakes and detritus — before it reaches the rest of the media.

When a fish tank filter’s pad tears or crushes, flow drops and the water turns cloudy. A fresh sponge is a quick, low-cost fix instead of replacing the whole hang-on unit.

Good to know:
– Measures 106×64×9.6mm — compare with your filter’s original pad to confirm the fit
– Spare sponge for Jingeye hang-on filters used on aquariums and fish tanks
– Rinse in tank water, not tap water, to protect beneficial bacteria
– Check your filter model before ordering — pads differ by size
