If i were going to go with a closed loop system I would look at the Red Dragon II with the ocean simulator. Or at least a variable speed pump then you can do more with it.

OK....just my 2 cents here...
Nobody has yet to mention the safety issue of having ph's placed in the tank. Can be a "shocking" situation if something faults and you do not have the right protection in place (GFI outlet for example). I am a "purist" as well when it comes to tank appearance. I would rather go with a cl and a sump than have a single ph or heater in my display tank (which is the way I am planning my 90 g). As for current...does anyone here run a SCWD cl? Is it worth it?

I agree with you: normal powerheads take up a lot of tank realestate. But I like my new vortech. I wanted a clean look in my tiny 45g tank and a single vortech did the job. If you ran one on each side it would look cleaner than the pipes sticking out from a closed loop and then you could have wavy looking action that'll make the polyps of your LPS and softies look cool.
It's hard to directly flow from a closed loop unless you start using locline and then you're starting to get clutter in the tank again. Vortechs pretty much don't need to be pointed.

Those vortecs look perfect for my system. Do you think two of them with the two little giants would be enough for my 230 gal tank? Or could I get away with one of them?

A SCWD is a water Switch Current Water Director
http://www.jlaquatics.com/phpstore/s...uct_ID=wm-scwd You could hook a couple up to each Little Giant and create some nice random movement. Just make sure you make it easy to take them off and clean them when they get jammed with debris. I try to go for 30-50 times of flow in a tank so for a 230 gallon I would aim for 6900-11500 GPH of turn over. 2 Little Giants and 2 Vortecs would be 7500 GPH. Probably enough for LPS and softies. You can always add 2 more when you are ready to try some higher flow corals  .You could also think about adding a maxi-jet mod if there are dead spots at the back of the tank after everything is set up. http://www.jlaquatics.com/phpstore/s...ID=wp-mpsf1600 You can hide them pretty easily and they are darn cheap.
