Brightwell Aquatics Xport NO3 Brick Ultraactivated Denitrification Brick Media doped with Elemental Sulfur for Superior Performance in Filtration Media XPBRICNO3

Use one XPort NO3 Brick for every 1, 000 U. S. gallons (3, 800 L) of system capacity, more for heavy bio loads. Normally do not use more than one brick per 100 gallons of tank capacity. Bricks may be cut in half for smaller systems. Rinse material well with aquarium water or purified tap water to remove any dust. For superior results, seed the material using only the specific bacteria product that you are using in the aquarium. If using Micr?Bacter Start XLM, use one capful to seed (add balance of bacteria directly to the aquarium). If using FlorinBacter7, Micr?Bacter7 or Micr?BacterCLEAN add full recommended dose. Place XPort NO3 Brick in a plastic container, filling it with aquarium water, and then adding the bacteria to that container. Allow to stand overnight and then add the seeded XPort NO3 Brick to your system. It is recommended that you use sponge, fine filter floss or other mechanical filtration ahead of XPort NO3 Brick to prevent clogging with organic material. For maximum results, also provide a good carbon source for growing bacteria, such as Brightwell Katalyst bio pellets or liquid Reef BioFuel or Florin Axis, as appropriate for your aquarium, as directed on their labels. Note: Xport is the best bacterial media in the world, but it is not good at gas exchange. Bio balls are the best for gas exchange, so any system will work better with a small stack of bio balls placed in the main flow (in air).
