Macroporous carbons remove primarily larger organic molecules such as nitrogenous waste and are best suited to water filtration. It has a very low ash content and minimal impact on pH, not raising pH above 7.0 even in distilled water. It has the lowest detectable leachable phosphate content of all major carbon brands tested, and outperforms other high grade carbons by at least two-fold in total capacity to remove aquarium organic matter, rate of adsorption, and duration of use.\u003c\/p\u003e\n\u003ch4\u003eDirections\u003c\/h4\u003e\u003cp\u003e250 mL will easily treat 400 L (100 US gallons) for several months. Use in a filter bag. Rinse before use. For best results, MatrixCarbon should be placed so as to maximize the flow of water through it.
