we have a 2-3" layer of sand and aragonite mixed and are going to buy another 5 lbs of live sand.

We were reading about the berlin method and would really like to use as much natural filtration as possible.

would like to grow some coral eventually as well.

as far as fish, we are not sure what to start with...thought about some green chromis and maybe a tang or two eventually
not sure what sps/clams/lps, andsofties are though.
and I am getting ro water from the fish store down the street like 50 cents a gallon.
