Also wanted to add a response to someone above who posted that this sounded like a recipe for disaster.
I work in a job that requires me to be away for sometimes up to a week. After owning a skimmer, and several "gadget" tanks, I think that a simple tank is less prone to breakdowns than one that has a bunch of gear plugged into it. If you read the forum long enough you'll read a lot of "co2 probe malfuntcioned, causing my PH to go haywire" "Temp probe went out, tank is 500 degrees, want some acropora crispies?" "skimmer went wacko, causing auto topoff to dose 500 gallons of prime well water"
and on and on.
If you do it right, a minimalist tank is more stable and predictable than a supergizmo tank by far, and less work too. Also cheaper.
Here's the problem though:
I wouldn't recommend a minimalist tank for beginners. You have to know how to read your tank and respond to what's going on. You have to know how to stock appropriately and not rush things. You can do a much better job once you have a few years of reefkeeping under your belt.
Just my opinion.
