Offered in a range of convenient sizes, Diamond Filtration Media works faster, longer, better. Performance tested and certified effective by Marineland Labs™, each has been compared against the leading brands of chemical filtration media.
Black Diamond Premium Activated Carbon eliminates discoloration, odors, and
impurities...and keeps on doing it long after other carbons quit. Heat-activated bituminous coal-based Black Diamond granules are specially sized and far more efficient than inferior coconut, wood or peat-based carbons. Premium Black Diamond works as much as twice as fast as the competition.

Excellent product by spiro09/26/2013
Excellent product and service. Makes my tank extremely clear and clean. Thank you.
A great value! by Michael from Richmond, VA04/01/2013
Compared to other products, this one was 3-5 times a better value, than the others! Why some sellers want so much money for activated carbon, I don't know. I've used the others and am very glad to have stumbled across this great value!
Great price great products by Screavics from Paron, AR06/09/2011
I bought this big tub of activated carbon because I make my own filters using the aquarium bulk filter rolls you can buy and a sewing machine. There is a lot more than I thought there was going to be and it was much cheaper than buying it at a big box store.
