My tank is a 16 gallon Biocube. Right now I am not satisfied with my aquascape. I have three pieces of dry rock I want to put in my tank. My question is can I add all three pieces in at once or should I do it more slowly? I am also wondering how I should prepare it to go into my tank. Should I just wash it in RO water or is there more I should do to it?
These are the pieces of rock
