Product description

Product Description Brightwell Aquatics XPort NO3 Brick is a revolutionary ceramic filtration media designed to improve water quality by effectively reducing nitrates, phosphate, and dissolved organics. Ideal for marine, reef, hard freshwater, and pond aquariums with a pH of 7.5 or higher, this high-performance brick features an ultra-porous structure doped with elemental sulfur. This advanced composition accelerates nitrate reduction while providing an expansive surface area—over 100,000 square feet per brick—for biological activity. The brick's unique design promotes both aerobic and anaerobic processes, supporting efficient nutrient processing. Its aragonite doping stabilizes pH levels, preventing acid buildup that can compromise filtration efficiency unlike competing products. The XPort NO3 Brick is also engineered to retain moisture for several days when drained, ensuring biological viability even during equipment downtime. Whether you have a small freshwater setup or a large marine reef tank, this versatile filtration media enhances water clarity, supports biological balance, and ensures long-term stability for thriving aquatic life. Directions Use one XPort NO3 Brick for every 1,000 U.S. gallons (3,800 L) of system capacity, more for heavy bio loads. Rinse material well with aquarium water or purified tap water. For superior results, seed the material using FlorinBacter, MicrōBacter7 or MicrōBacterCLEAN, as appropriate for your aquarium, by placing XPort NO3 Brick in a plastic container, filling it with aquarium water, and then adding the full recommended dose of either bacterial product, based on the size of your aquarium, to that container. Allow to stand overnight and then add the seeded XPort NO3 Brick to your system. You may also add the water back to your aquarium, if desired. 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 label.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
