PetWorx Replacement Sponge

Keep your aquarium clean and your filter performing at its best with the PetWorx 800 / 1300 / 1800 Replacement Sponge. Specifically designed for PetWorx internal filters, this high-quality sponge delivers reliable mechanical and biological filtration for a healthier aquatic environment.

The durable, fine-pore foam effectively captures debris, uneaten food, and waste, helping maintain crystal-clear water. At the same time, it provides an ideal surface for beneficial bacteria to thrive - supporting the natural breakdown of harmful ammonia and nitrites and promoting a stable freshwater ecosystem.

Available for PetWorx 800, 1300, and 1800 models, this replacement sponge ensures consistent filtration performance and optimal water flow.

To maintain efficiency, rinse the sponge in aquarium water during regular maintenance to preserve beneficial bacteria. Periodic replacement is recommended to keep your filtration system operating at peak condition.

Ensure long-lasting performance and a healthy aquarium with genuine PetWorx replacement sponges.
