Review on 🐟 22 Ounces of Marineland Black Diamond Premium Activated Carbon: Ideal Filter Media for Aquariums by Dawn Mattheis

Revainrating 4 out of 5

Works well well for fish and aquatic animals

Bought this just to see how it works. Basically, I water in bowls that I put in out-of-the-way corners in different rooms of the house, and it affects how fresh the rooms smell. I also put a tray made from this material in a new fridge I bought while waiting for the bags made from this material to arrive for another Revain order. Went like clockwork. Happy and will buy more

Pros
