Aquarium Filter Foam, 50x50x2 cm, Nitrifying Filter Sponge, Activated Carbon, For Freshwater and Saltwater

This aquarium filter foam offers optimal mechanical and biological filtration thanks to its medium-porosity structure. Made of high-density filter fiber, it effectively traps impurities and promotes the growth of nitrifying bacteria. This filter sponge can be cut to size to fit all types of filters, ponds, or hydroponic systems. Washable and reusable, this activated carbon filter ensures clear water and a stable biological cycle for your freshwater or saltwater aquarium. Dimensions: 50 x 50 x 2 cm Color: Black Quantity: 1 piece Material: High-density filter fiber

Medium porosity structure is ideal for developing nitrifying bacteria and trapping waste and food residue. Made of thickened, ultra-dense fibers, this filter sponge does not deform and remains permeable after washing. It accelerates the decomposition of impurities to reduce fish mortality and stabilize the aquatic environment.

Measuring 50x50x2 cm, it can be easily cut to fit internal and external filters, ponds, and hydroponic systems. Maintenance is simple: rinse monthly with clean water to extend the life of the filter cotton and keep the water clean.
