Rinse the new cartridge under tap water before fitting to clear any loose carbon dust.\u003c\/p\u003e\u003ch3\u003eSuitable for, and not suitable for\u003c\/h3\u003e\u003cp\u003eSuitable for freshwater and marine tanks running a Fluval Nano filter where water needs polishing after medication, tannin staining, or general odour and discolouration control. Not a substitute for mechanical or biological filtration — always run alongside the foam pad and Bio-Foam, not instead of them. Remove carbon before dosing most medications, as it will absorb them.\u003c\/p\u003e\u003ch3\u003eWarranty and delivery\u003c\/h3\u003e\u003cp\u003eConsumable item; if a pack arrives damaged or faulty, it's covered under your rights as an Australian consumer.

Carbon will absorb most medications along with the impurities it's designed to remove, reducing the treatment's effectiveness. Take it out before dosing and put a fresh one back in once the course is finished.\u003c\/p\u003e\u003ch4\u003eDoes this replace the foam pad?\u003c\/h4\u003e\u003cp\u003eNo. It's an additional chemical media that sits alongside the foam pad and Bio-Foam already fitted to the filter, not a replacement for either.\u003c\/p\u003e","brand":"Fluval","offers":[{"title":"Default Title","offer_id":55293309059363,"sku":"NAN21C","price":7.95,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0972\/7236\/5347\/files\/NAN21c_1.png?v=1782880077","url":"https:\/\/nicksaquariumoceanariumterrarium.com.au\/products\/fluval-nano-aquarium-filter-carbon-cartridge","provider":"Nicks Aquarium Oceanarium Terrarium","version":"1.0","type":"link"}
