This replacement filtration sponge is intended for use with the Ultum Nature Sytems Delta 90 or 120 Canister Filter. We cannot guarantee compatibility with alternative aquarium filtration units.
A thick and high-quality reusable green sponge is placed in the initial chamber as a solid form of mechanical filtration. This is to prevent detritus, more commonly known as fish waste and aquatic plant matter from building up within the following filtration chambers. Simple to maintain, this fine-textured sponge can be easily taken out for cleaning and popped back in quickly. The sponge should be cleaned on a regular basis and will remove larger sized organic waste.
TIP: Keep multiple replacement sponges and have them ready to quickly swap out during aquarium canister filter maintenance.
