• Single-pore sponge You will receive a set of 12 black pre-filter sponges, each measuring 4 cm long x 8 cm in diameter (1.57 x 3.15 inches) with a center pore size of 2 cm (0.79 in). This size is carefully designed to be compatible with a variety of common aquarium filter models. For best results, please carefully measure your filter inlet size before purchasing to ensure a perfect fit and optimal filtration performance
• High-efficiency filtration This pre-filter sponge effectively intercepts large debris such as food scraps, fish waste, and plant debris in the water, preventing them from clogging the main filter. This significantly reduces the burden on the filtration system and extends the life of the filter media. By pre-removing large particles, it helps maintain clear and stable water quality, creating a healthier living environment for your aquarium
• Safety barrier The installation of the filter sponge effectively disperses and weakens the suction at the filter inlet, forming a soft safety barrier. This perfectly prevents small aquatic creatures such as fry, shrimp, and betta fish from being accidentally sucked in, making it especially suitable for use in breeding tanks, shrimp tanks, or aquariums housing small ornamental fish, providing a safe and worry-free habitat for all aquarium dwellers
• Superior and Durable Material The sponge is made of high-density, highly elastic, safe aquarium sponge, soft and fluffy, and will not obstruct normal water flow. The product is vacuum-packed and may deform due to compression upon first use; simply soak it in warm water for a short time to fully restore its original shape. The sponge can be repeatedly washed and reused, effectively reducing long-term maintenance costs
• Easy to Clean and Widely Applicable Installation is extremely simple; simply slip the sponge over the filter inlet. For cleaning, simply remove the sponge during water changes and gently rinse it with the squeezed-out aquarium water to remove dirt—quick and easy. This sponge is suitable for both freshwater and saltwater aquariums and is an essential accessory for every aquarium enthusiast to improve filtration efficiency and ensure the safety of their fish
