I made a purchase of 50 lbs of base rock from Marcos which by the way was a smart move. Very beautiful base rock. But this question is for people who have purchased from there. I was wondering if the same amount of marcos base rock was equivalent to the amount of live rock you recieved. 50 lbs Live Rock = 50 lbs Base Rock or is the live rock heavier than base and if I order 50 lbs of live rock should I expect the same amount of rocks as the base rock or a lesser amount b/c of weight.
