Carbon (kolar labs/Calgon) from saltwateraquarium

[zedxplorer]

Any one uses this? I usually run the fluval one from PetSmart and it has been working for me.

This seems to be much more economical in the long run with a 5g bucket but want to see if anyone tried this before I get a big tub of it.

This seems to be a spec sheet from Calgon, the actual manufacturer, looks like it is carbon from bituminous coal used for liquid processing. Safer than lignite?
