The best way to find LR cheap is to catch someone in the act of breaking down and parting out their tank. I bought about 40 lbs from some guy in Mason for 2 dollars a pound. Good stuff too!!! Very porus. I would have bought more but ran out of cash. If you decide to order online I may go in on some with you and just split the cost. SWF has pretty good fiji for a nice price. I prefer Marshall Island though.
