Its complex pore system gives beneficial bacteria a large surface to colonise, which is what keeps ammonia and nitrite under control. One caution: this is living media, so rinse it in aquarium water rather than tap water, and stagger changes instead of replacing everything at once, or you strip the bacteria colony out of the tank.\u003c\/p\u003e\u003cp\u003eFluval recommends rinsing monthly and replacing every three months, and most keepers order it with the \u003ca href=\"\/products\/fluval-spec-flex-evo-replacement-carbon-3-x-45g\"\u003eFluval Spec \/ Flex \/ EVO Replacement Carbon 3 x 45g\u003c\/a\u003e that shares the same chamber.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFits\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpec\u003c\/strong\u003e — 10 L and 19 L (2.6 and 5 US Gal)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEVO\u003c\/strong\u003e — 19 L and 52 L (5 and 13.5 US Gal)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlex\u003c\/strong\u003e — 34 L, 57 L and 123 L (9, 15 and 32.5 US Gal), and Flex 2.0 34 L (9 US Gal)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBetta kits\u003c\/strong\u003e — 10 L and 22 L (2.6 and 6 US Gal)\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eComplex pore system\u003c\/strong\u003e — A larger surface area for beneficial bacteria to grow on than smooth media offers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eControls ammonia and nitrite\u003c\/strong\u003e — Supports the bacteria that reduce and control both toxins.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMesh bag\u003c\/strong\u003e — Lifts out in one piece for quick, tidy maintenance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFresh or salt\u003c\/strong\u003e — Suitable for freshwater and saltwater aquariums.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eRinse\u003c\/strong\u003e — Monthly, in aquarium water\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReplace\u003c\/strong\u003e — Every 3 months\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFluval part #\u003c\/strong\u003e — A1378\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e — 015561113786\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003ca href=\"https:\/\/fluvalaquatics.com\/us\/product\/spec-evo-flex-biomax\/\" rel=\"nofollow noopener\" target=\"_blank\"\u003eView this product on the Fluval website\u003c\/a\u003e\u003c\/p\u003e","brand":"Fluval","offers":[{"title":"Default Title","offer_id":55952431612226,"sku":"FLUVAL418","price":7.09,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0563\/6676\/0120\/files\/spec07.jpg?v=1787217549","url":"https:\/\/www.peekapaw.com.au\/products\/fluval-spec-flex-evo-replacement-biomax-42g","provider":"PeekAPaw Pet Supplies","version":"1.0","type":"link"}
