These four foams serve the canister's 0.5 litre pre-filter chamber — the first thing tank water meets on its way into the filter. Their job is to catch leaf litter, uneaten food and coarse debris before any of it reaches the fine wool, the carbon or the biological media further down.\u003c\/p\u003e\n\n\u003ch3\u003eWhy the pre-filter stage matters most\u003c\/h3\u003e\n\u003cp\u003eEverything downstream lasts longer when the pre-filter is doing its job. Coarse debris that gets past this stage settles into the fine wool and the ceramic media, where it decays, restricts flow and forces a full strip-down of the canister to fix.\u003c\/p\u003e\n\u003cp\u003eA pre-filter foam is designed to be pulled, rinsed and put straight back. Bioscape's own instruction is to rinse the pre-filter media monthly to maintain strong flow.

Heavily stocked or heavily fed tanks will need it more often, because this is the stage that catches all the coarse debris. Rinse in a bucket of aquarium water rather than under the tap.\u003c\/p\u003e\n\u003ch4\u003eWhy will my pre-filter lid not come off?\u003c\/h4\u003e\n\u003cp\u003eIt is almost always an airlock rather than a jammed lid. Bioscape's instruction is to slightly loosen the red cap on the inlet to admit a few air bubbles, which releases the vacuum and lets the lid lift off easily. Levering at it risks cracking the lid.\u003c\/p\u003e\n\u003ch4\u003eDo the foams need replacing on a schedule?\u003c\/h4\u003e\n\u003cp\u003eNo. Bioscape publishes a monthly rinse interval for pre-filter media but no fixed replacement interval. Replace a foam when it stays compressed after rinsing, tears, or no longer seals across the chamber, since debris then bypasses the stage entirely.\u003c\/p\u003e\n\u003ch4\u003eWill BIS540C fit the 1620 or 2000 L\/h canister?\u003c\/h4\u003e\n\u003cp\u003eNo. The pre-filter chambers are different sizes: 0.5 L on the 1050 L\/h, 0.8 L on the 1620 L\/h and 1.0 L on the 2000 L\/h. Those two models take BIS541C and BIS542C respectively.\u003c\/p\u003e\n\u003ch4\u003eCan I rinse the foams under the tap to save time?\u003c\/h4\u003e\n\u003cp\u003eIt is better not to. Even coarse pre-filter foam carries beneficial bacteria, and chlorinated tap water kills it. A bucket of water siphoned out during your water change costs nothing and keeps the colony alive.\u003c\/p\u003e","brand":"Bioscape","offers":[{"title":"Default Title","offer_id":55293066182947,"sku":"BIS540C","price":20.95,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0972\/7236\/5347\/files\/bioscape-1050l-h-canister-re-43179167711523.webp?v=1790234718","url":"https:\/\/nicksaquariumoceanariumterrarium.com.au\/products\/bioscape-1050l-h-canister-replacement-top-pro-filter-foam-4","provider":"Nicks AOT","version":"1.0","type":"link"}
