Review on Premium Activated Carbon for Aquariums - MarineLand Diamond Media, 40-Ounce (PA0373) by Natalie Wright

I purchased this activated charcoal (or charcoal) in July 2015 and have only used a cup or so over a year later. A 40 ounce container will serve us forever. It can be used for aquarium and water filtration, odor removal, skin care masks and more. I bought it for teeth whitening (google activated charcoal for teeth whitening if interested). It's very messy in terms of white shell stains or whatever if you're not careful. A coffee grinder or food processor will help with grinding (since you will need teeth whitening powder). We have separate toothbrushes ready for this. We kept it closed in a cool and dry place and it's still like new. Made in the USA. Good product and excellent value for money. Recommended. Upload some photos so you can take a closer look and estimate their size. To smile. Hope this is helpful!
