I have a question about it now. Right now I have 25 lbs of regular sand in it, and 40 lbs of Agro Live sand in it. But there is no life in the sand no hichhikers nothing that could be dead. My question is this would it be safe to add my coral (mind you it is dead and bleached so it won't be decaying any farther) then in a week or so add some snails to get the cycleing started? Would this work? Or is it pointless? Just wondering. I want to do this right, but I don't want to wait a month or so add some fish to tank I thought was safe then for everything to die. Thanks!
