{"product_id":"hollow-bio-beads","title":"Hollow Bio Beads","description":"\u003cmeta charset=\"UTF-8\"\u003e\n\u003cspan data-mce-fragment=\"1\"\u003eHOLLOW BIO BEADS is a biological filter material with an innovative, patented hollow design that promotes the formation of deep-seated denitrification zones. Made of inert ceramic, it has a large usable surface area of ​​approximately 700 m2\/L. Thanks to Open Porosity™ technology, it has a unique structure with open macro-pores that ensures perfect colonization and simultaneously delays clogging, extending maintenance times. Its shape allows for a different distribution of NH+4 and NO-2 ions, which can therefore be actively absorbed. It has a low impact on TDS and does not alter the pH value (pH 7\/7.5). Most of the pores are located in the 45\/55 µm to 10 nm range, meaning the surface is biologically and truly usable for bacterial colonization.\u003c\/span\u003e\u003cbr data-mce-fragment=\"1\"\u003e","brand":"AQPET","offers":[{"title":"500ml","offer_id":40028751790189,"sku":"","price":15.79,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0555\/6453\/3869\/products\/A2B60F7B-BB49-4EDB-9171-07894C354A6D.jpg?v=1650404620","url":"https:\/\/animal-instinct.it\/en\/products\/hollow-bio-beads","provider":"Animal.Instinct","version":"1.0","type":"link"}
