Marineland PA0372 Black Diamond Activated Carbon, 22-Ounce, 624-Gram

I use this for the storage room that has bunch of shoes, it helps decrease the smell and the stuffiness of the room even with the door closed. I also use it for my diaper pail for my baby and helps lock the smell in for days. Good quality and good amount for the price

Decent amount of carbon for the price, way cheaper than filter pre-built bags with sprinkles of carbon in them. Very easy to use just dumping into a mesh bag fitting whatever needs you have and functioning the way you need it to be. Isn't dirty and just needs a simple rinse to get activated and wash off some dust

Cheaper than most and works just as good.

We work hard for the money and are happy with this move getting this carbon. The container was larger than I anticipated (22oz here). Outstanding activated carbon at a great price. I've been a fish tank caretaker for over 30 years and imho it rinses clean fairly quickly, and yes indeed you hear that rice krispies snap cackle pop sizzle coming from the carbon right after rinsing it which is a great sign of great quality. I am first using this for cat fountains with mesh zipper bags not filter material and it does not slip through the 1-layer mesh, so rocks are small but large enough it should not be an issue with say, whisper bio bags.

Very good value for your buck. I use it for my fish filters and to keep the air fresh in the litter box room.
