I am new to salt water and I am setting up a fowlr 55 tank. I have been reading everything on this site to get me prepared... My lfs has some nice live rock but is either $8 / lb or $15/lb depending on how much "stuff" is growing on it. Due to their prices I cannot afford 75lbs of this stuff. I was thinking of buying some dried/dead rock from Marco's rocks then seeding it with some of the live rock from my lfs. Will this work? Also, I have seen mixed reviews on Marcos rocks, has anyone ordered from him lately and were you treated fairly? Last question, do I add the aragonite or substrate before or after the live rock?
