This size container is very economical. We have a large aquarium and have purchased mesh bags that are reusable. We can fill them many times with this container and use in our filter.

I've been mixing a small amount of this into the clay litter for years. It stops smells completely. People coming into my house don't smell cats and I've got four indoor only fur babies.
I've been buying food from Chewy's for several years and I was thrilled to discover that they have this carbon.
great & thank you.

Thank you..exactly what I needed. Also, I truly appreciated the neo-therm cobalt heater replacing the one that the face blew off.
What a fantastic surprise...Thank you.

Black diamond is some of the best phosphate free carbon on the market marineland uses this same carbon in their filter packs an I have been using it for decades without an issue.

I use this product in conjunction with Seachem's Purigen, but alone, it packs quite the punch! I don't regularly use this product in my filters, rather, only when I need to take out medications, or to help polish the water column after I do a messy water change. This product makes the water nice and clear, sometimes, over the span of a few hours.
It's a bit dusty, and needs a good rinsing before you add it to your media bags, but that's to be expected with any charcoal!
