This is the spare filter board for the Jingeye JY-W255 hang-on filter. The board sits inside the filter chamber and supports the sponge and media, so a warped, torn or cracked one is the first part to replace when flow through your aquarium or fish tank filter starts to drop.

A new board is a low-cost fix that keeps the filter running instead of replacing the whole unit.

Good to know:
– Fits the JY-W255 — the 400L/h model in Jingeye’s hang-on range; check the model number on your filter before ordering
– Supports the sponge media inside the filter chamber of hang-on aquarium filters
– Pair it with a fresh sponge if the pads are tired too
