Its generous sponge surface provides plenty of space for mechanical dirt retention and colonisation by biologically active filter bacteria while maintaining gentle water movement.\u003c\/p\u003e\n\u003cp\u003eThe filter is operated by an external air pump. The air-lift principle ensures continuous water flow through the sponge while simultaneously supporting oxygenation of the aquarium. Despite its high filtration capacity, the NSF-C350L operates quietly and without its own electric motor in the water.\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ch3\u003eTechnical data\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eModel: \u003cstrong\u003eNSF-C350L\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003eFor aquariums up to approx. \u003cstrong\u003e350 litres\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003eDimensions: approx. \u003cstrong\u003e28.5 × 15 × 11 cm\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003eEAN: \u003cstrong\u003e5904378738846\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003eAir-driven corner sponge filter\u003c\/li\u003e\n\u003cli\u003eEspecially large filtration and colonisation surface\u003c\/li\u003e\n\u003cli\u003eMechanical and biological filtration\u003c\/li\u003e\n\u003cli\u003eGentle water movement and additional oxygenation\u003c\/li\u003e\n\u003cli\u003eQuiet, robust and low-maintenance operation\u003c\/li\u003e\n\u003cli\u003eEasy-to-clean filter sponge\u003cbr\u003e\u003cbr\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cem\u003eAn air pump and suitable airline tubing are required for operation and are not included.\u003c\/em\u003e\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003cstrong\u003eManufacturer information\u003c\/strong\u003e\u003cbr\u003eEURONOVA POLSKA Sp. z o.o.\u003cbr\u003e(owner of the AQUA NOVA brand)\u003cbr\u003e87-330 Jabłonowo-Pomorskie\u003cbr\u003eKonojady 94B\u003cbr\u003ePoland\u003cbr\u003eTel.: +48 56 4980008\u003cbr\u003eEmail: tf@aqua-nova.pl\u003c\/p\u003e","brand":"Aquanova","offers":[{"title":"Default Title","offer_id":55311784902983,"sku":"NSF-C350L","price":8.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0901\/3588\/8199\/files\/aquanova-nsf-c350.jpg?v=1791317979"}],"url":"https:\/\/terboven-aquaristik-shop.live\/en\/collections\/schwammfilter-innen.oembed","provider":"Terboven Aquaristik","version":"1.0","type":"link"}
