Bioscape supplies two white wool pads and one blue pad with every canister in the PRO range — the 1050, the 1620 and this one. The pads get physically larger as the canister body does, but the count does not change, while the rated tank volume more than doubles from 250 litres to 600.\u003c\/p\u003e\n\u003cp\u003eThe practical consequence is that on a well-stocked 600 litre tank, the fine wool tends to reach the short end of Bioscape's 4 to 6 week window rather than the long end. Wool that has gone brown and stiff before the four-week mark is not a defect. It is the pad reporting your stocking level, and it should be changed when it gets there rather than at a date on the calendar.\u003c\/p\u003e\n\u003cp\u003eWhat you do have on this model is generous biological reserve. The BIS542 carries 11.0 litres of media — the largest in the range — and is uniquely supplied with two ceramic noodle packs and two bio-ball packs, where the smaller canisters get one of each. Your bacterial colony does not live on the white wool. Changing it is a low-risk service on this filter in a way it would never be on a small hang-on unit.\u003c\/p\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003ePart number\u003c\/th\u003e\n\u003ctd\u003eBIS542A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSKU\u003c\/th\u003e\n\u003ctd\u003eBIS542A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePack contents\u003c\/th\u003e\n\u003ctd\u003e2 white fine filter wool pads, 1 blue foam\/wool pad\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFits\u003c\/th\u003e\n\u003ctd\u003eBioscape PRO Easy Clean Canister Filter 2000 L\/h (BIS542) only\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHost filter rating\u003c\/th\u003e\n\u003ctd\u003eAquariums up to 600 L\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHost media capacity\u003c\/th\u003e\n\u003ctd\u003e11.0 L\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHost filter dimensions\u003c\/th\u003e\n\u003ctd\u003e280 x 280 x 500 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eStage\u003c\/th\u003e\n\u003ctd\u003eFine mechanical filtration\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eBioscape service interval\u003c\/th\u003e\n\u003ctd\u003eReplace fine wool every 4 to 6 weeks\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWater type\u003c\/th\u003e\n\u003ctd\u003eFreshwater and marine\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eWhich PRO canister do I have?\u003c\/h3\u003e\n\u003cp\u003eThe three PRO canisters have different body sizes, so the pads are cut differently and do not interchange.

One pack is a complete refill of the fine mechanical stage.\u003c\/p\u003e\n\u003ch4\u003eHow often should the white wool pads be replaced?\u003c\/h4\u003e\n\u003cp\u003eBioscape specifies replacing fine wool every 4 to 6 weeks across the PRO canister range. On the 2000 L\/h model, which services tanks up to 600 litres with the same three pads supplied to the smaller canisters, heavily stocked setups will reach that point at the shorter end. Change the pads when they stay brown and stiff after a rinse rather than waiting out the full six weeks.\u003c\/p\u003e\n\u003ch4\u003eCan I rinse the white pads instead of replacing them?\u003c\/h4\u003e\n\u003cp\u003eOnce or twice, to stretch the interval. Fine wool is dense by design and loses its structure as it is squeezed, so it stops catching the fine particles it exists to trap. A pad that stays discoloured and compressed after rinsing is restricting flow rather than filtering.\u003c\/p\u003e\n\u003ch4\u003eWill replacing the white pads crash my cycle?\u003c\/h4\u003e\n\u003cp\u003eIt should not on this filter. The BIS542 carries 11.0 litres of media and is supplied with two ceramic noodle packs and two bio-ball packs, so the bulk of the bacterial colony lives well away from the fine wool. Leave the blue pad and the biological media undisturbed during the change and the colony carries through comfortably.\u003c\/p\u003e\n\u003ch4\u003eWill BIS542A fit my 1050 or 1620 L\/h Bioscape canister?\u003c\/h4\u003e\n\u003cp\u003eNo. The 1050 L\/h BIS540 takes BIS540A and the 1620 L\/h BIS541 takes BIS541A. A quick way to confirm which you have: the 2000 L\/h is the only PRO canister on 19\/25 mm hose, while the other two share 16\/22 mm.\u003c\/p\u003e\n\u003ch4\u003eMy water is still hazy after fitting new pads. What now?\u003c\/h4\u003e\n\u003cp\u003eCheck the 1.0 litre coarse pre-filter above them, which is the usual culprit, then the lid seal and the impeller. Persistent fine haze that survives clean mechanical media is often a bacterial bloom rather than a filtration fault, and that clears on its own once the tank stabilises.\u003c\/p\u003e","brand":"Bioscape","offers":[{"title":"Default Title","offer_id":55293067329827,"sku":"BIS542A","price":32.95,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0972\/7236\/5347\/files\/bioscape-2000l-h-canister-re-43179169382691.webp?v=1790234718","url":"https:\/\/nicksaquariumoceanariumterrarium.com.au\/products\/bioscape-2000l-h-canister-replacement-sponges-2-white-1-blue","provider":"Nicks AOT","version":"1.0","type":"link"}
