【Mechanical Filtration】 Filter cotton effectively traps and removes suspended particles, debris, uneaten food, fish waste, and other solid impurities from the water. It acts as a physical barrier, capturing larger particles on its surface and preventing them from re-entering the tank. This helps to maintain clearer and cleaner water. 【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. 【Effective Filtration】 The biochemical cotton filter foam sponge media roll pad enhances water quality by capturing debris and impurities, creating a healthier and cleaner habitat for your aquatic pets 【Universal Fit】 Suitable for various aquariums and fish tanks, including sea water tanks, fresh water tanks, and aquatic tanks, providing versatile filtration solutions 【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. Please unpack and let the pads sit for 24-48 hours or soak in the water before use for best results.
