Aqua One Filter Sponge for Reflex 13 Aquarium Kit

This Replacement Sponge is tailored to fit the Aqua One Reflex 13. The sponge insert strains solids like uneaten food and fish waste from the aquarium water, and should be replaced every 8 weeks to ensure peak tank conditions and crystal clear water. We recommend only using Aqua One genuine spare parts in their range of aquariums.
