MarineLand Diamond Media Premium Activated Carbon, Blacks & Grays, 40-Ounce (PA0373)

Good one

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

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.

Cheaper than most and works just as 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.
