Bioscape supplies the BIS542 canister with two activated carbon packs, and BIS542B is sold as a single pack, so a complete carbon change means ordering two. This differs from the 1050 and 1620 L\/h models, which are each supplied with one carbon pack.\u003c\/p\u003e\n\u003ch4\u003eHow often should the BIS542B carbon be replaced?\u003c\/h4\u003e\n\u003cp\u003eBioscape specifies replacing fine wool and carbon every 4 to 6 weeks across the PRO canister range. Carbon shows no visual sign of exhaustion, so the change is made on the calendar rather than on appearance. A pack left in for months occupies media space without adsorbing anything.\u003c\/p\u003e\n\u003ch4\u003eWill BIS542B fit my 1050 or 1620 L\/h Bioscape canister?\u003c\/h4\u003e\n\u003cp\u003eNo. The 1050 L\/h BIS540 takes BIS540B and the 1620 L\/h BIS541 takes BIS541B. The 2000 L\/h is the largest body in the range, with 11.0 litres of media capacity against 6.5 and 9.0 litres, and its media is cut accordingly.\u003c\/p\u003e\n\u003ch4\u003eDoes activated carbon remove medication from the tank?\u003c\/h4\u003e\n\u003cp\u003eYes, and it is the most common reason a treatment appears to fail. Carbon adsorbs most aquarium medications, frequently within hours of dosing. Remove both packs before starting a course, then fit fresh carbon once the course is finished to clear the leftover residue.\u003c\/p\u003e\n\u003ch4\u003eCan I run the canister with only one carbon pack?\u003c\/h4\u003e\n\u003cp\u003eYes, it will do no harm. You are simply running half the chemical capacity the filter was designed around, so tannins, odours and medication residue in a tank of up to 600 litres will take longer to clear. For general maintenance one pack is workable; for a specific job, fit both.\u003c\/p\u003e\n\u003ch4\u003eCan I recharge or reuse the carbon pack?\u003c\/h4\u003e\n\u003cp\u003eNo. Baking, boiling or rinsing spent aquarium carbon does not restore its adsorption capacity. Once the adsorption sites are occupied they stay occupied, and the pack should be replaced.\u003c\/p\u003e","brand":"Bioscape","offers":[{"title":"Default Title","offer_id":55293067297059,"sku":"BIS542B","price":29.95,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0972\/7236\/5347\/files\/bioscape-2000l-h-canister-re-43179169349923.webp?v=1790234720","url":"https:\/\/nicksaquariumoceanariumterrarium.com.au\/products\/bioscape-2000l-h-canister-replacement-carbon-cartridge-1-pack","provider":"Nicks AOT","version":"1.0","type":"link"}
