Great way to economize aquarium filter cleaning
Buying filter carbon cartridges for both canister or aquarium filters that hang on the back can get expensive. This is a way to reduce the cost by buying the activated carbon in bulk, then purchasing mesh zip up bags to fill. (Bags are not included). On jar of this carbon will fill a lot of bags making the cost of the filter change nearly nothing. I have noticed that it takes a long time to rinse out this carbon though. Seems to be a lot of dust. It takes me about a minute or more of rinsing to get clean water through it. I have had other filter carbons rinse clean in 10 to 15 seconds. Overall though it works fine with just a little more work up front.

One of the best values in activated carbon
Good value. Not the cheapest, but it's also one of the highest quality, made with lignite and not cheap coconut fiber. Won't cause HLLE in fish. Also can be used in rodi Filter.

Excellent value
After wasting so much $ at the large “P” stores on fish aquarium essentials, starting to get items in bulk. Excellent charcoal.

Works good for my purposes
I bought this as I couldn’t find acid free carbon. I soaked it over overnight in water and baking soda to neutralize the acid. I then dried it in a dehydrator for a few hours. It worked good for lowering the VOCs for my 3D printer.
