BRS Bulk Small Particle Lignite Carbon is a great option as a general water polisher and is very effective at removing yellowing pigments, contaminants and irritants from your tank. Both our Small and Large Particle Lignite carbon offer very good performance and are priced to be a great value. We purchase our carbon directly from the manufacturer so we can offer the best carbon at reasonable prices. While most companies claim their carbon is the best, our statement is backed with true science and real numbers.

  • Small Particle has more surface area and is slightly more effective than Large Particle, but with more dust.
  • Large Particle is has wider compatibility with different reactors and will clog more slowly.


BRS Lignite Carbon will outperform competing brands for less. The primary function of carbon is to remove color pigments, pollutants, and medications from an aquarium. Each these contaminants has a larger molecule structure and requires a carbon with a pore size large enough to effectively remove them. Our Lignite Carbon contains a high number of large pores capable of removing these molecules.


BRS Bulk Lignite Carbon Specifications

  • Molasses Decolorizing efficiency 85 MIN
  • Dust% 0.40 Max
  • Iodine Number 625
  • Surface Area M2/g 650
  • Total pore Volume mL/g 0.95
  • Washed with Hydrochloric Acid
  • Food Chemical Codex: Passes


Instructions: We recommend 1 Tablespoon of BRS Small Particle Lignite Carbon per 8 Gallons of tank water either placed in a media bag, or reactor.

SPECIAL NOTE: Lignite carbon contains more dust because it is softer. Be gentle when rinsing and do not tumble the material in a reactor which will create more fines. Carbon is most effective at slow flow rates. For a harder carbon with low dust please try BRS Premium ROX 0.8 Carbon.


Different carbons are not created equal. Different sizes, shapes, and materials will perform with drastically varying results. Check out our Carbon Quick Compare Chart below before deciding on the best carbon for your saltwater system.

Product Questions

What mesh size is this carbon?
Question by: Taylor on May 18, 2016, 2:44 AM
Great question!
These will work in mesh filters up to 500 micron well. Our standard mesh will work great!

Which Bulk Catalytic Activated Carbon is equivalent to that provided in your Chloramine filter kit?
Question by: Bob on Oct 2, 2013, 10:22 PM
Hi Bob,
It is actually different from all of the aquarium carbons. Because the surface activated carbon for chloramines is used in the RO units its actually in the RO/DI filters category and can be found at the link below:
