It is formed as a spherical bead for optimum hydrodynamics, and will not pack. It permits maximum water flow and contact with its high density of macroporous binding sites. MatrixCarbon has a very low ash content as indicated by its minimal impact on pH. Even when added to distilled water, it does not raise pH above 7.0. While all carbons contain phosphate, regardless of false claims to the contrary, MatrixCarbon has the lowest detectable leachable phosphate content of all major carbon brands tested. MatrixCarbon outperforms other high grade carbons by at least two-fold when compared for total capacity to remove aquarium organic matter, rate of adsorption, and duration of use.\u003c\/p\u003e\n\u003cp\u003eWhy is Matrix Carbon Different?\u003cbr\u003eWhile carbon is generally considered to be a chemical filter, that is not precisely true. It is in fact a mechanical filter as well, but it is only capable of mechanically filtering objects of molecular size. It functions through extremely small cracks and crevices, called macropores and micropores. Microporous carbons remove primarily metals and smaller ions (like trace minerals) and are best suited to air filtration, while macroporous carbons remove primarily larger organic molecules (like nitrogenous waste) and are best suited to water filtration.\u003c\/p\u003e\n\u003cp\u003eThe ingredients from which a carbon is manufactured determine whether it will be macro- or microporous. Carbons made from coconut shell and other organic products form microporous carbons, while carbons made from bituminous coal form macroporous carbons. MatrixCarbon is a bituminous coal-based, macroporous carbon. It is the only spherical carbon on the market, allowing for maximum water flow. It is sized to allow full penetration by water, but not small enough to escape filter bags. All carbons contain phosphate. However, that phosphate does not come from washing the carbon with phosphoric acid. Most carbons are washed with sulfuric acid. The phosphate is contained in the ash from the carbon source. The main purpose of acid-washing is to remove ash. Because of MatrixCarbon’s hydrodynamic properties, more ash is washed from our carbon than any other. Therefore, it has the lowest leachable phosphate on the market.\u003c\/p\u003e\n\u003cp\u003eDirections:\u003cbr\u003e250ml will easily treat 400L\/100 gallons for several months. MatrixCarbon is very clean and nearly dust free. For best results, MatrixCarbon should be placed so as to maximize the flow of water through it. It may be used in a canister filter, chemical filtration module, box filter, or any high flow area of a trickle filter.\u003c\/p\u003e\n\u003cp\u003eTechnical Specifications:\u003c\/p\u003e\n\u003cp\u003e    Shape: Spherical\u003cbr\u003e    Mean Diameter: 2.39 mm\u003cbr\u003e    Density: 0.49 g\/cc\u003cbr\u003e    Pore Volume (PV): 0.55-0.65 ml\/cc\u003cbr\u003e    Total Surface Area (TSA): 500-600 m²\/cc\u003cbr\u003e    TSA\/PV: 770-1100 m²\/ml\u003cbr\u003e    Iodine: \u0026gt;1000\u003cbr\u003e    Molasses: \u0026gt;600\u003cbr\u003e    pH in distilled water:\u003c\/p\u003e","brand":"Seachem","offers":[{"title":"Default Title","offer_id":44044692979800,"sku":"000116010702","price":40.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0712\/8557\/1672\/files\/58308-84fd4d1fbcfa3cdeb95f702ce6212a6fd411047e_grande-1.jpg?v=1779082227","url":"https:\/\/bespokeaquariums.com.au\/products\/seachemmatrixcarbon1l","provider":"Bespoke Aquariums","version":"1.0","type":"link"}
