Review on 🐠 Enhanced Aquarium Filter Carbon API: Efficaciously Eliminates Organic Waste, Colors, Odors, and Enhances Water Clarity. Suitable for Regular Use in All Types of Aquarium Filters by Valarie Bennett

Used as a filter layer over rocks to create succulent terrariums. It currently costs just over $6 a half gallon, free shipping as an add-on (I order six boxes), making it the best product out there. It has some dust in it, but the size of the pieces is perfect for my purposes. Dust is not harmful to terrariums, but rinse thoroughly before using in aquarium filters as directed on the packaging. I tried another cheaper brand but the grainy chunks were too big for me.
