I have a 40 breeder and I am setting up a 120. Can I take my rock fish and 3 corals I have in the 40 breeder and put them in the 120 and add sand later? I am almost finished with the drilling and such but I want to use black sand and it will about a month before I can get it. Is it possible to add 120 lbs of sand to a take with fish? YouTube doesn't have what I am asking so whay do I do?
