{"product_id":"seachem-matrix-500ml","title":"Seachem Matrix 500ml","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\u003cspan\u003e2\u003c\/span\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\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\u003ch4 class=\"heading-primary\"\u003eDirections\u003c\/h4\u003e\u003cp\u003eUse 250 mL of Matrix™ for each 200 L (50 US gallons)** of water. Matrix™ may be placed in any kind of filter, and is particularly effective in a canister filter. Matrix™ is sufficiently large that no filter bag should be required for most applications. Matrix™ works well in drip tray systems, but you may find that the larger Pond Matrix™ is better suited for such applications. Use with \u003ca href=\"https:\/\/seachem.com\/stability.php\"\u003eStability®\u003c\/a\u003e to more rapidly establish the bio-filter.\u003c\/p\u003e\u003cp\u003e**This dosage may differ from your packaging. Based on updated studies, we've found Matrix™ treats even more water than previously asserted.\u003c\/p\u003e","brand":"Seachem","offers":[{"title":"Default Title","offer_id":57054408409419,"sku":"SEACHEM-MATRIX500","price":13.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1033\/7065\/4027\/files\/0_2_0207641_2_66.jpg?v=1776422338","url":"https:\/\/krakencorals.co.uk\/products\/seachem-matrix-500ml","provider":"Kraken Corals","version":"1.0","type":"link"}
