Within a short time a bacteria lawn develops on the media. These bacteria feed on dirt particles of all kinds and convert substances that are critical for the health of your aquarium.\u003c\/p\u003e\u003cp\u003eBiological filtration is the most important stage after the first cleaning step carried out by mechanical filter media such as EHEIM MECH or MECHpro. It helps keep water clear and healthy and keeps water values stable.\u003c\/p\u003e\u003cp\u003eThis pack contains 830g, approximately 1 litre, of media and suits EHEIM external and internal filters.\u003c\/p\u003e\u003cp\u003eCare tip: never clean or replace all of your filter media in one go, and avoid cleaning too rigorously. The bacteria cultures must not be completely destroyed, otherwise re-colonisation will be slower.\u003c\/p\u003e","brand":"Eheim","offers":[{"title":"Default Title","offer_id":67987549683938,"sku":"EH2509051","price":44.95,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0066\/1284\/4602\/files\/eheim-substrat-filter-media-830g-1l-2509051-1.png?v=1794568756","url":"https:\/\/reefsecrets.com.au\/products\/eheim-substrat-filter-media-830g-1l-2509051","provider":"Reef Secrets ","version":"1.0","type":"link"}
