{"product_id":"pond-matrix-2ltr","title":"Pond Matrix 2ltr.","description":"\u003cp\u003ePond Matrix™ is a high porosity biomedia that provides efficient biofiltration for the removal of nitrogenous waste in ponds. Plastic bio-materials provide only external surface area, whereas Pond Matrix™ provides internal macroporous surface area. These macropores are ideally sized for the support of nitrifying and denitrifying bacteria. This allows Pond Matrix™, unlike other forms of biomedia, to remove nitrate along with ammonia and nitrite, simultaneously and in the same filter. Pond Matrix™ is completely inert and will not breakdown. It need not be replaced. It is also more suitable for use as a clean soil replacement for growing pond plants. Use 1–2 Liters of Pond Matrix™ for each 100 US gallons. Since the majority of the bacteria are internal, Pond Matrix™ may be rinsed when needed without damaging the filter. Pond Matrix™ is compatible with all types of wet or wet-dry filters.\u003c\/p\u003e\n\u003c!----\u003e","brand":"Seachem","offers":[{"title":"2 L","offer_id":44990463115427,"sku":null,"price":37.0,"currency_code":"USD","in_stock":true},{"title":"4 L","offer_id":44990463148195,"sku":null,"price":54.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0660\/8797\/7123\/files\/2119-Pond-Matrix-4-L.png?v=1722021625","url":"https:\/\/extrememarine.myshopify.com\/zh\/products\/pond-matrix-2ltr","provider":"extreme marine","version":"1.0","type":"link"}
