Login to Review »
Product Description:
Marineland Black Diamond Aquarium CarbonBlack 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.

Available in 5oz, 10oz, 22oz and 40oz.

"It's better than standard filter pad carbon!"
I like to put it in the extra media trays I bought for my Penguin. The carbon seems a bit more dense, and has more surface area in this pelleted form.

-Oops the Carbon I have is when it was named Magnum carbon

"Excellent Carbon!"
Black Diamond is a great carbon BUT I think it worked better when it was called Magnum Carbon. This Black Diamond is a little too small as it seems to tear up my magnum impellers because it's brittle enough at the smaller size to get thru the carbon container. The Magnum never did because of it larger size.So I guess if your Marineland and need to sell more magnets and impellers then this size works well for the company

"IMO over priced"
Its ok like most carbon, but i find its way over priced for the work it does, so i started buying carbon in pellet size by the cubic foot, so much cheaper and of the same quality, not to mention small carbon gets in your impellers, depending on what filter system you have...

"Seems to work as it should."
I don't use carbon on a regular basis. Instead I only add it to remove medication. I buy this carbon in bulk and save money. Can't really say how well it works.
