It all boils down to the amount of money you want to spend, and amout of time you are abe to invest in tank maintenance. You could have a FO w/LR or have a reef tank with organisms that don't need bright lighting or the most pristine conditions, or if you have money to upgrade you culd purchase more lighting, lots of top-grade LR and live sand (saltwaterfish.com has some very good package deals), a big skimmer and have a magnificent reef tank with fragile organisms, and striking fish! It's up to you!
