I'm planning on starting a 70G RR tank with a sump. I know the preferred amount of LR is between 1.5lbs to 2.0lbs per gallon. In order to reduce my startup expenses, I'm thinking about buying some dry rock (like the ones from reefer rock). Now, when doing my weight to water ratio calculation, should I count the dry rock as LR or should I count it separately in order to try to get more bacteria to start?
