About this item

• Mechanical Filtration: PPI: 20. The aquarium filter media pad can effectively trap debris, food residue, wastes or other impurities in water. Prevent them from entering the aquarium to keep water clean
• Fine Sponge Filtration: With larger contact area with water, the black filter media sponge is helpful for the accumulation of beneficial elements. Provide biological filtration to fully remove excess damaging substances
• Versatile Use: Size: 20" L x 20" W x 1" H. The filter floss roll can be cut to fit all aquarium filters, such as wet/dry filters, canister filters, power filters, etc. Also work great for sumps or ponds
• Reliable Material: The filter media sponge is made of soft and foldable foam with high elasticity and fine air and water permeability. No worry about sucking up your fish. And it won’t block the normal water flow due to the fluffy inner structure
• Easy to Use: Rinse it with cool water to remove any dust, cut to size, and place fully in the filter chamber. Replace every 2-4 weeks for optimal water quality. (Please unpack and let it stand for 24-48 hours or soak in water before use for best results.)
