220 Gallon tank blank slate, do i take the plunge?

I don't think I've seen tanks that large run without sump...drilling is a must in my opinion. With FO you'll have hungry and potentially larger fish making more waste. Skimming will help you out a ton there.

Water changes will certainly be more expensive at that size...I'm not sure how cheap you could run the tank but skimming more aggressively might mean you can do fewer changes saving some money long-term.
