This thicker black sponge pad is a replacement for Jingeye hang-on aquarium filters, cut to 145×58×30mm. The extra depth gives more room to trap detritus and more surface for the beneficial bacteria that keep a fish tank’s water stable.

A worn or crushed pad is one of the common reasons flow drops in a hang-on filter, and a fresh sponge costs far less than replacing the whole unit.

Good to know:
– Measures 145×58×30mm — 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, when swapping it in
