How does this koi pond carbon compare with your premium activated carbon aquarium filter charcoal media?

Our Premium activated carbon and Pond carbon are both made of bituminous coal which has been heat-treated making it active. Which is a perfect material to remove organics from water. For Pond carbon, this is where the process ends, but for our Premium carbon, it goes through a series of cleaning steps making it cleaner to trap contaminants and toxins from your aquarium and pond water. When carbon is activated the pores are packed with ash that a simple rinse will not wash away. Our cleaning process removes most of the ash giving a ton more room for the carbon to grab more contaminants. Another benefit is the carbon is clean.
