Its carbon. Pellets look nice. Seems to do the job well. Less dust than other carbons. Priced well.

I actually run this on my aquarium 24/7 in a mesh bag in my sump. I'm about to use a reactor for it, but I can tell a difference in smell and clarity once it's used up. As a matter of fact, if I wait longer than month to change the carbon, my skimmer will overflow in my living room because the nutrients were released back into the water. I used to be against carbon use in reef tanks because I believed it stripped the water of essential trace elements. Studies actually prove that a protein skimmer will remover much more elements than activated carbon. I wouldn't run a reef without it.
