Fish Safety Sponge Filter Replacement Cover Protects delicate aquarium inhabitants: Designed to fit securely over your filter intake, this foam cover prevents small fish, shrimps, fry, and other vulnerable species from being drawn into the filtration system. Maintains clean and healthy water: The sponge efficiently traps debris, uneaten food, waste particles, and plant matter before they reach the main filter, helping to sustain a balanced aquatic environment. Durable and reusable: Made from soft, safe, and elastic foam, this prefilter can be rinsed clean and reused multiple times without losing shape or performance, ensuring long service life. Allows strong water flow: The material structure supports water circulation while still filtering out unwanted particles. Simple installation: The preformed hole allows quick fitting directly onto most standard filter intakes. For larger sponge sizes, a piece of string or aquariumsafe tie can be used to secure the fit. Practical uses: 1. Ideal for shrimp breeding tanks where even small juveniles require protection from filter suction. 2. Suitable for fry growout aquariums to safeguard young fish during early stages. 3. for community tanks with mixed species, ensuring weaker or slowmoving inhabitants remain safe while maintaining water clarity.
