Now that is a quality basic setup, no crap gear and the fish/coral will be happy for years, no need to upgrade in 4 months.
I probably mist a few things, very light on livestock, and items like salt mix, etc,
Could be done a bit cheaper, but at least there is a good chance the fish/coral will be alive in 12 months.
If going fish only you could save a$1000 or so.
