1. Yes
2. Calgon is not the name of a carbon but a company that makes carbon and a gia-zilion other chemicals. Think Dupont. Calgon is like saying buy a GMC or a Dupont.
Almost all Bitum GAC is Calgon but they do have some Liginte. Almost all Lignite GAC is American Norit but they do have some Bitum.
Where can you get it is not that easy.
First, which one of the many Calgon GAC's is it. The number of GAC typies they make will fill a book
You are lucky it is Lignite or it would take you a year to figure out which one
You will not be able to buy it direct, so you are stuck with a supplier. Second, will they sell you a small amount. These guys sell it by the truck load or 55 gal drums or 25 lb bags or so.
This is Calgon's GAC page

And the Liginte comes form Barnebey Sutcliffe. Their new website sucks, as 75 % of the GAC types they make are not even there. Barnebey Sutcliffe specializes in Lignite, Wood and Coconut GAC. You will have to e-mail or call them to see which one it "might" be :lol:
Never seen any PO4 issues to worry about. Make sure you rinse
well all GAC.
