Brightwell Aquatics Xport BIO Dimpled Brick - Xport – the premier filtration media in the world!

Xport-BIO Ultra-porous Biological Media with Superior Performance Characteristics.


  • Utilizes NanoIntelex Technology to create an enhanced material with vast surface area for colonization by beneficial nitrifying bacteria, resulting in rapid and efficient conversion of ammonia into nitrite and nitrate.
  • The highest colonizable surface area to volume ratio of synthetic biological filtration media available.
  • Higher efficiency relative to conventional media results in smaller space requirements to achieve equivalent nitrification.
  • May be employed to rapidly decrease ammonia and nitrite concentrations in even the most heavily-stocked aquatic systems.
  • May be used in conjunction with Xport-NO3 and Xport-PO4

  • Nominal 9" x 4.50" x 2.50" for Aquascaping, Biofiltration, and Coral Propagation

    Because our material is not fired or heated, but chemically hardened:

  • Surface area over 10 times as high as any competing products (many times hundreds to thousands of times as high)
  • Wicks water and stays wet for days after a pump fails, allowing bacteria to remain alive much longer and be ready when a system upset is repaired.
  • We can dope it with sulfur, ferric oxyhydroxide or almost any other material to facilitate bacterial growth or remove pollutants
  • It contains coral aragonite powder to buffer pH and provide for bacteria life longevity.
  • We can make it in almost any shape and size - to fit a specific filter system.

  • Instructions and Guidelines

    Use one XPort Bio 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 well with the aquarium water or purified tap water. For superior results, seed the material using FLORINBACTER, MICROBACTER7 or MICROBACTER CLEAN as appropriate for your aquarium, by placing XPORT BIO 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 BIO 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 material. For maximum results, also provide a good carbon source of growing bacteria, such as Brightwell KATALYST bio pellets or liquid REEF BIO FUEL or FLORIN AXIS as appropriate for your aquarium, as directed on their label.

    Yes, I would recommend this.

    Last about a year or so...

    Pros: Very porous

    Cons: crumbles with time

    Works well, and makes sump clean-up easy for the first year. At around 14mths, it started to crumble, and by a year and a half it was gone.

    Does its job

    Pros: lots of surface area

    Cons: some say it crumbles later

    Stays wet during sump maintenance, haven't had it long enough to see if it crumbles

    Just got it but seems to work

    I just got this but the pore space is great. I was using rock rubble from Caribe sea but it was collecting detritus and I wanted something in my sump I could clean out around it. This brick seems like it will work better. I will keep you updated on how it is doing in the future.
