【Durable Material】The filter bag is made of corrosion-resistant polyester and is completely safe for fish. The mesh does not clog with air bubbles and is odorless. It is resistant to bleach, caustic soda, and acids, improving water quality and extending the lifespan and efficiency of the filter material.

【Thoughtful Design】The plastic zipper protects the filter material, is reusable, and ideal for long-term use. Unlike metal zippers, which can easily rust and contaminate your water, this bag optimizes your filter and perfectly adapts it to the needs of your aquarium or pond, as well as your fish and animals. [Size] The aquarium filter bag measures 20 x 15 cm and has a mesh diameter of approximately 1 mm. The ultra-fine mesh is perfect for activated carbon, peat fibers, granules, bio-balls, zeolite, pellets, gravel, ceramic rings, ammonia removers, or other aquarium filter media. [Create an Ecological Water Environment] Place the extra-fine mesh bags with zippers, filled with your preferred filter material, into flowing water. This contributes to a high-quality habitat for your animals. Purified water, rapid growth of probiotics – restoring natural water quality is crucial. Your fish farming requires a good water supply and proper care. 【Package Contents】The package contains 10 filter bags and a zipper. This can be tightened to prevent loose filter material from damaging your water pump or the motor of your electric filter. This allows you to fill or empty the bags.
