1. [Excellent Filtration]: The aquarium filter mat has 8 layers of filtration environment: 2 pieces of 3D honeycomb woven cloth, 2 pieces of three-dimensional hydrophobic fiber cotton, 2 pieces of carbon fiber cotton, 1 piece of nano-biochemical cotton, and 1 piece of fiber biochemical cotton. The 3D honeycomb woven glands imprison larger particles, the three-dimensional hydrophobic fiber cotton imprisons fine particles, and the others filter extremely fine dirt and odors. All of these work together to provide efficient filtration. 2. [Improve Water Quality]: With an improved honeycomb shape design, the aquarium filter mat scientifically filters and absorbs harmful bacterial pollution, which can easily establish a nitrification system, stabilize the development of nitrifying bacteria, and provide clean water permeability for fish and other aquatic organisms. 3. [Environmentally friendly materials]: No harmful substances, no adhesives, no chemical odors. The aquarium filter rope with hot melt technology is an ideal choice for aquarium enthusiasts to ensure the safety of friends living in the water. .[Easy to Clean]: The aquarium filtration environment is made of a sturdy mesh fabric with a dense structure. Unlike other widely used filter sponges that are easily deformed or expanded after washing, our 8D filter sponge can withstand more than 200 washes without deformation. With 8D filter pads, you don't need to replace the filter pads frequently. 4.[Wide Application]: The pond filtration environment (can be cut into any size according to your needs, which can meet various requirements and save your money. It can be used in many types of filtration systems, such as filter pads, cartridge filters, hanging after filters, and wet and dry filters. Freshwater or saltwater aquariums, fish tanks, turtle tanks, pond filters, and aquaculture systems are all perfect choices.
