Frag Tank

[straightrazorguy]

I have a 33 gallon quarantine tank that I am thinking of converting into a frag tank. I have most of the parts, including a sump and a small skimmer, should I decide to use one. I am wondering if I should plumb it inline with the 150 gal display tank or I should have a standalone tank (as a completely different system). If separate, should it have a sump and skimmer? I could use it for corals only, or throw a fish in as a nutrient source. What do the experts recommend? I would like to keep it as simple as possible....
