About This

• Fine Sponge Filtration: With larger contact area with water, the black filter media sponges are helpful for the accumulation of beneficial elements. Provide biological filtration to fully remove excess damaging substances.
• Versatile Use: Size: 9" L x 9" W. 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, ponds or hydroponic systems.
• Reliable Material: The filter pads are made of soft and foldable foam with high elasticity and fine air and water permeability. No worry about sucking up your fish. And they won’t block the normal water flow due to the fluffy inner structure.
• Easy to Use: Before use, rinse the sponge with cool water to remove the outside dust, then cut it to the proper size and fully put it into the filter chamber. Replace it every 2 to 4 weeks to maintain a healthy water environment.
• Mechanical Filtration: The filter media pads can effectively trap debris, food residue, wastes or other impurities in water. Prevent them from entering the aquarium to keep water clean.
