MarineLand Black Diamond Premium Activated Carbon 22 Ounces, Filter Media For aquariums

Cheaper than most and works just as good.

Very nice stuff

This has been a great purchase. It has made our drinking water tast great. I have also used it in our fish tank and has made a massive difference. The fish look alot more at home with much cleaner water.

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

Good one

Good

I recently used the Marineland Black Diamond Premium Activated Carbon in my aquarium, and the difference is remarkable. My turtle’s water went from murky and gross to crystal clear in no time. This carbon filter media is easy to use—all it takes is a thorough rinse under water to prevent any black residue, and it’s ready to go. The product is reliable and safe for my turtles, maintaining a clean and healthy environment in their tank. I find that rinsing the carbon every few months keeps the water consistently clear. Overall, this is a dependable and effective product that I will continue to use for my turtles’ aquarium.
