Fresh foam is the cheapest way to keep a hang-on filter working properly. This yellow sponge is the replacement media for the Jingeye JY-W155, the 250L/h model in the hang-on range, so a tired pad can be swapped without replacing the whole filter.

It suits nano aquariums and small fish tanks run with the JY-W155 hang-on filter. The yellow foam catches larger debris and helps keep the water looking clear.

Good to know:
– Direct fit for the Jingeye JY-W155 (250L/h) — check the model number on your filter before ordering
– The JY-W range has several sizes — the model number is what matters
– Rinse the new sponge in old tank water before fitting to protect beneficial bacteria
