Replacement Tube Bio Sponge (XY-2820 Series) for Your Xinyou Filter

This is the genuine replacement sponge cartridge for the Xinyou tube-style bio sponge filters in the 2820/2821/2822/2830 range. We stock spares deliberately, because the smartest way to clean a sponge filter is to never let it fail you: keep a spare on hand so you can swap rather than scrub a sponge that has finally collapsed or torn. The foam carries both your mechanical filtration and the bulk of your beneficial bacteria, so its condition directly affects water stability.

For Singapore keepers, the key tip is to stagger your replacement. Never change every sponge at once, and never rinse a new one under chlorinated tap water, or you will wipe out the bacterial colony and risk an ammonia spike in our fast-souring warm tanks. Instead, seed a new sponge alongside the old one for a couple of weeks, or squeeze old tank water through it before relying on it fully.

Find compatible spares under filter media, and read our filter media guide. To avoid a cycle crash when swapping, see our nitrogen cycle troubleshooting guide.
