Brightwell Aquatics Xport-No3 Cubes – ½” Cubes, Sulfur Doped, Activated Denitrification Media

The Xport-NO3 Cube is designed to be used in marine and hard freshwater aquariums with a pH of 7. 5 or over. This denitrifying filtration media eliminates the need to perform water changes that are carried out for the express purpose of decreasing nitrate in an aquarium system. The Xport-NO3 cubes utilize NanoIntelex Technology to create an enhanced ultra-activated material with the capacity to outperform conventional denitrification media by over 300%. Provides over 71 000 square feet of usable surface area per liter of cubes. This leads to higher efficiency results in smaller space requirements to achieve equivalent denitrification.
