{"product_id":"matrix-500-ml","title":"Matrix","description":"\u003cp\u003eMatrix™ is a high porosity biomedia that provides efficient biofiltration for the removal of nitrogenous waste. Matrix™ is a porous inorganic solid about 10 mm in diameter. Each liter of Matrix™ provides as much surface (\u0026gt;~700 m\u003csup\u003e2\u003c\/sup\u003e) as 170 liters of plastic balls! Plastic bio-materials provide only external surface area, whereas Matrix™ provides both external and internal macroporous surface area. These macropores are ideally sized for the support of nitrifying and denitrifying bacteria. This allows Matrix™, unlike other forms of biomedia, to remove nitrate along with ammonia and nitrite, simultaneously and in the same filter.\u003c\/p\u003e\n\u003cp\u003eMatrix™ is completely inert and will not breakdown. It need not be replaced. Since the majority of the bacteria are internal, Matrix™ may be rinsed when needed without damaging the filter. Matrix™ is compatible with all types of wet or wet-dry filters.\u003c\/p\u003e\n\u003c!----\u003e","brand":"Seachem","offers":[{"title":"500 ml","offer_id":44989514350755,"sku":"000116011303","price":12.0,"currency_code":"USD","in_stock":false},{"title":"1 L","offer_id":44989514383523,"sku":"000116011304","price":17.0,"currency_code":"USD","in_stock":false},{"title":"2 L","offer_id":44989514416291,"sku":"000116011305","price":33.0,"currency_code":"USD","in_stock":false},{"title":"tidal 35","offer_id":44989514449059,"sku":"000116011306","price":9.0,"currency_code":"USD","in_stock":true},{"title":"tidal 55","offer_id":44989514481827,"sku":"000116011307","price":10.0,"currency_code":"USD","in_stock":true},{"title":"tidal 75","offer_id":44989514514595,"sku":"000116011308","price":13.0,"currency_code":"USD","in_stock":true},{"title":"tidal 110","offer_id":44989514547363,"sku":"000116011309","price":17.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0660\/8797\/7123\/files\/0118-Matrix-2-L.png?v=1722020430","url":"https:\/\/extrememarine.myshopify.com\/zh\/products\/matrix-500-ml","provider":"extreme marine","version":"1.0","type":"link"}
