Ok I know the difference between live and base rock in general. But i dont really know the specifics. Does dead base rock provide the same filtration as live rock? Typically how long does it under the right condition(calcium content?) for the seeding process to start and actually turn you base in live? Im planning in having 250-300 lbs of total rock in my tank. I was thinking 100lbs of live rock mostly to cover the face of my reef and the rest base rock. Does this sound like a reasonable amount. Im going to get the best available live rock that I can afford but I just am not going to be able to afford to buy the total weight live (at least I dont think). What are my options? Thanks Ryan
