Just got several things in bulk from bulk reef supply dot com. Carbon, kalk and GFO. Can't beat the prices! 4.5lbs of kalk for the same price as a half lb of kent kalk!
The carbon is ROX o8, 950 iodine, ash mass of 3%
What do you think z? good stuff?

probably one of the better lignite based activated carbons you can find but a really short longevity (aka will work like gangbusters for a week before its maxed out) but does contain heavy metals that may be associated with leaching in trace amounts. {realize this amount if probably far less than cheap activated carbon bought in local fish stores, I would say its about 7 steps up from API store bought carbon)
the ash mass isnt really as important as the water soluble ash levels, unfortunatly information like that is really hard to track down unless your a member of a scientific research institute (believe me I ran into about a dozen brick walls) they want 14$ for an article that details it since I'm not a member.
