About this item

• For 15-55 Gallon Tanks: Measuring 6" W x 9.5" H, this aquarium sponge filter fits perfectly in 15-55 gallon freshwater or saltwater tanks. Perfect for the breeding and feeding of fry, shrimp, or various ornamental fish
• Gentle Mechanical Filtration: The porous sponges gently capture visible debris, uneaten food, fish waste, and other impurities without restricting water flow. Help keep water crystal clear and provide a cleaner habitat for your aquatic pets
• Deep Bio Filtration: Both bio sponges and ceramic rings provide ample surface area for beneficial elements to thrive. Boost biological filtration to absorb and eliminate harmful substances and maintain a clean, stable, and healthy aquatic environment
• Air-Powered & Silent: Work quietly with an air pump and 3/16" tubing (both not included) to produce dense bubbles, boosting oxygen circulation for fish’s well-being. Remove the 2 extra sponges from the filter chamber and add the ceramic rings before use
• Easy to Use & Maintain: Quick to assemble and detach for easy cleaning. Keep the sponges fully submerged. Rinse every 2 weeks with aquarium water only to protect the helpful elements on the surface. Never use tap water
