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 Lauren Lewis

I received a box of black pebbles and dust. It's too bad for a decent filter. Also, the water in my tank turned black no matter how many times I rinsed and soaked it. This is the WORST charcoal I've used in all my years of keeping fish, but that's what I get for trying to save a few bucks by buying an API product. Now I have black fingers, a black sink, a black tub, black buckets, black water from the tank, and a filter with a black rock in it. I threw the whole box of this nonsense in the trash.
