Bio Sponge Filter for Aquarium – Premium Filtration Solution
High-density bio sponge ensures superior mechanical and biological filtration, trapping debris while promoting beneficial bacteria growth for crystal-clear water. Dual-layered sponge design with ultra-fine pores (30-50 PPI) maximizes surface area, enhancing waste absorption and oxygen diffusion in freshwater or saltwater tanks. Whisper-quiet operation with adjustable air flow, ideal for breeding tanks, shrimp habitats, or hospital aquariums where gentle filtration is critical. Durable ABS construction with reinforced base prevents floating, and the non-toxic, PH-neutral sponge ensures safe use for delicate species like bettas or fry. Easy maintenance with a squeeze-cleaning feature; compatible with most air pumps (requires airline tubing) for versatile setup in nano to medium-sized aquariums. Compact submersible design saves space while providing efficient filtration—perfect for planted tanks, quarantine systems, or low-flow environments.
