The biofiltration process breaks down toxic ammonia and nitrites, preserving a clean, healthy habitat for your fish. CAF sponge filters are weighted and easy to install with an air pump or powerhead (sold separately), which provides airlift for silent operation. CAF filters may be used as standalone, breeding, or secondary filters, and will fit most external or top filters to act as prefiltration units.Directions: When performing routine maintenance, save a portion of removed aquarium water in a fishsafe container. Disassemble the sponge filter and separate the sponge from the hardware. Use the saved aquarium water to clean the sponge. Squeeze it, shake it, and rinse it out in the fishsafe container. When the sponge looks clean, reassemble the sponge filter and reinstall.Specifications:CAF10:Aquariums up to 10 gallons60 pores\/linear inchDiameter: 2 (base); 2 (sponge)Uplift tube height: 1.5Sponge height: 1.75Full height: 3.5Uplift I\/D: 9\/16CAF25:Aquariums up to 25 gallons40 pores\/linear inchDiameter: 2.75 (base); 3.125 (sponge)Uplift tube height: 3Sponge height: 3.5Full height: 6.75Uplift I\/D: 3\/4CAF40:Aquariums up to 40 gallons40 pores\/linear inchDiameter: 3.25 (base); 5 (sponge)Uplift tube height: 3Sponge height: 3.5Full height: 6.75Uplift I\/D: 3\/4CAF60:Aquariums up to 60 gallons40 pores\/linear inchDiameter: 3.25 (base); 5 (sponge)Uplift tube height: 3Sponge height: 5.5Full height: 8.5Uplift I\/D: 3\/4CAF180:Aquariums up to 180 gallons35 pores\/linear inchDiameter: 3.5 (base); 6.5 (sponge)Uplift tube height: 6Sponge height: 7.75Full height: 13.75Uplift I\/D: 1Includes free air stoneCAF250:Aquariums up to 250 gallons35 pores\/linear inchDiameter: 3.5 (base); 8.5 (sponge)Uplift tube height: 6Sponge height: 7.75Full height: 13.75Uplift I\/D: 1Includes free air stone\u003c\/p\u003e","brand":"Aquatop","offers":[{"title":"Default Title","offer_id":54602280436078,"sku":"WBPETB00S556UO2","price":103.72,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0901\/9575\/5374\/files\/at01254__1.jpg?v=1787054176","url":"https:\/\/petocart.com\/products\/aquatop-caf-classic-aqua-flow-sponge-filter","provider":"Petocart","version":"1.0","type":"link"}
