Fluval doesn't publish a specific replacement interval for BioMax; as a ceramic media it typically lasts years rather than months, and only needs replacing if it physically breaks down or a basket needs freeing up.\u003c\/p\u003e\n\u003ch3\u003eSuitable for, and not suitable for\u003c\/h3\u003e\n\u003cp\u003eSuitable for freshwater and saltwater systems with a canister or sump basket for biological media.

Like any new biological media it starts without a bacteria colony, so add it to an established, already-cycled filter where existing media can seed it.\u003c\/p\u003e","brand":"Fluval","offers":[{"title":"500gm","offer_id":55293293494563,"sku":"FA44","price":15.95,"currency_code":"AUD","in_stock":false},{"title":"1100gm","offer_id":55334984941859,"sku":"FA48","price":27.95,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0972\/7236\/5347\/files\/fluval-biomax-rings-43313878761763.webp?v=1790238521","url":"https:\/\/nicksaquariumoceanariumterrarium.com.au\/products\/fluval-biomax-rings","provider":"Nicks AOT","version":"1.0","type":"link"}
