Two-piece aquarium filter cover, stainless steel filter, cotton filling available, aquarium inlet protection (16 mm).

Package includes: 2 filter grids and 2 sponges. The grids prevent small fish and shrimp from being sucked into the filter and dying. Material: Stainless steel, sponge. Avoid contact with welded seams when hand washing. The grids may become deformed during transport; gently squeeze them to regain their original shape. Dimensions: The filter grids measure 8.5 x 3 cm with an inner diameter of 16 cm. The sponges measure 6 x 3.5 cm with a pore size of approximately 1.5 cm. This filter prevents larger particles, aquatic plants, and leaves from being sucked in. Easy to use: The shrimp filter covers are easy to use and fit directly into the inlet pipe for hard water. They effectively prevent small shrimp and fish from being sucked in and extend the lifespan of the filter media. Application: This shrimp filter is suitable for various external filters with an inlet pipe diameter of approximately 12 or 16 mm. It helps clean the inlet pipe, reduces debris buildup, and minimizes flow loss.
