Fish Safety Sponge Filter: The replacement foam cover attaches to the aquarium filter intake to protect shrimps, fry, or weaker residents from being sucked into the filter.
Filter Impurities: The inlet sponge filter effectively traps debris, food residue, waste, plants, and other impurities to maintain a healthy water environment.
Reusable: The pre-filter sponge for aquarium is made of soft, safe, and highly elastic foam that can be easily rinsed and reused, allowing for a large water flow.
Easy Installation: Each aquarium filter sponge has a hole for direct fitting onto the filter. If the sponge is relatively large, a rope can be used to tie it tightly.
Size: With a length of 8.7cm/3.4 inches, outer diameter of 5cm/2 inches, and inner diameter of 2cm/0.8 inches, this fish tank filter sponge is not suitable for filters over 2 inches in diameter.
