That's why i asked, you can't aim them towards the center. I'd be a little dissapointed if I spent that much and found that the Koralias provided a more random pattern.
I'm in the middle of my latest build, a 30x30x24 cube. I was just going to go with 2 Koralia 4's on the back wall angled towards the center of the front glass. Now I'm thinking of Vortechs instead. Mainly to keep the motors out of the water, smaller intrusion, and battery back-up ability. I...
Not familiar with the Milwaukee but I have been advised that this is one of the best around:

I had the Reef Fanatic regulator and it was trouble free as well.
I don't put much stock in the watts per gallon rule.I believe it has more to do with how far the corals are from the light, how deep they are.

If you do 3 400w bulbs you can keep anything you want in the tank. As far as T5's or VHO's or PC's, no, you don't have to. You should be able to find the color you are looking for with the MH bulbs.
What do you want the appearance of the tank to be? White, blue, white with a touch of blue?

Yes, the great SE vs. DE debate. I used 250w DE on my 180 and they were great. I'm building a 30x30 tank now and will be using a SE 400w bulb. There are as many opinions on SE vs. DE as there are bulb choices. My reasons for going SE this time are, more bulb choices, especially in the 400w...
The problem is that silicone does not bond to plexi. But, if you use a generous amount of silicone it will act as a wedge and hold the plexi in place. I used it in a 20 long as well and it worked just fine.
Is the 210 6 feet long? If it is, you would probably be better off with 3 250w lights. Or 3 400w depending on what you plan to keep. I don't think 2 lights will give you the best coverage.
I was really concerned with the flow pattern. Seams the Tunze has a narrower flow stream and the Koralia a broader more gentle flow. I'm trying to keep cost down or I would just go with a pair of 6101's.
Anyone have any experiences with the new controllable Koralias?
The Tunze 6045 and Koralia 4 have about the same output (1200gph). Which would be better for a 30x30x24 tank? Main inhabitant to be a Gigantea anemone.
I got the go ahead to start up a small tank. She won't let me have another 180 >:(. So, I have decided on a 30x30x24 (about 90g).I can't seem to find anyone who sells this size besides custom places, so I'm building it myself.
For lighting I picked up a full size Lumenarc, 400w Lumatek ballast...
