Marineland Black Diamond Activated Carbon Filter Media eliminates discoloration, odors and impurities for sparkling clean water, and continues to do so long after other carbons quit. These heat-activated bituminous coal-based Black Diamond granules are specially sized for optimum effectiveness and are ideal for all aquarium filters. They work twice as fast and are far more efficient than coconut, wood or peat-based carbons.

Sadly, I no longer have fishies since we hit the road in our RV full time. I use this charcoal to stuff old socks to stash in closets, drawers, and cargo compartments, and it works great for that. The bay where we stow our pupper supplies no longer reeks of old dog foot. LOL. I also use it in the bottom of our planter pots.
Large container for a great price

Use this in my house plants. It's nice and fine and much better buy than the little container from the store.

I really like this carbon media for my aquarium filter. Easy to use. Great value for the quantity and quality.
Good buy but a lot of work

Great deal for the money but be prepared to spend 20-30 minutes rinsing then gravel. There’s an unbelievable amount of dust in the package.

Works great in any tank size, more cost effective to refill and wash out the bags in filters rather than the pre-filled bags. Lasts much longer with a greater volume when you fill and refill yourself.

I use this for extra filtration bags in my larger tanks. Adds a few weeks to filter changes.
