Within a short time a bacteria lawn develops on the media, feeding on dirt particles of all kinds and converting substances that are critical for the health of the aquarium.\u003c\/p\u003e\u003cp\u003eBiological filtration is the most important stage after the first cleaning process carried out by mechanical filter media such as EHEIM MECH or MECHpro. It helps provide clear, healthy water and stable water values.\u003c\/p\u003e\u003cp\u003eThis pack contains 1660g, approximately 2 litres of media, suited to EHEIM external filters and compatible internal filter modules.\u003c\/p\u003e\u003cp\u003eCare tip: never clean or change all of the filter media in one operation, and avoid cleaning too rigorously. The bacteria cultures must not be completely destroyed, otherwise re-colonisation will be slowed.\u003c\/p\u003e","brand":"Eheim","offers":[{"title":"Default Title","offer_id":67987554599138,"sku":"EH2509101","price":79.95,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0066\/1284\/4602\/files\/eheim-substrat-filter-media-1660g-2l-2509101-1.png?v=1794568787","url":"https:\/\/reefsecrets.com.au\/products\/eheim-substrat-filter-media-1660g-2l-2509101","provider":"Reef Secrets ","version":"1.0","type":"link"}
