The XY-1810 Filter Sponge is a high-quality filtration media designed to provide mechanical and biological filtration for both freshwater and marine aquariums. Measuring 32 × 12 × 2 cm, this sponge efficiently traps debris, uneaten food, and waste particles, keeping water clean and clear while promoting the growth of beneficial bacteria for natural biological filtration. The XY-1810 Sponge is compatible with most filter systems, including canister filters, hang-on-back (HOB) filters, and sump setups. Its durable, reusable design allows for long-term use, and it can be easily cut to fit smaller filter compartments without losing effectiveness. Thanks to its open-cell structure, water flows smoothly through the sponge, preventing clogging and reducing maintenance frequency. The sponge can also be combined with other filtration media such as ceramic rings, biochemical mats, or activated carbon to enhance water quality and stability.
