Deepwater and Regular Acro Help

Well, after 2 years in the hobby, its finally (hopefully) time for an upgrade. The new tank will be a sexy 85 wide rimless (36"x26"x22") and in keeping with the theme, it will be a BB tank with no refugium. Oversized skimmer, ATO dosing Kalk and perhaps pellets or MB7. Yes I want this to be ULNS since I want to get into smoothskin/deepwater (think A. suharsonoi, A. echinata). Well I've been hearing conflicting advice:
Some say that they should be kept under ledges and in actinic light
Others say they can color up in higher light
So where should I place them?
The lighting (for now) will be 1 250w MH with either 15K or 20K bulbs (help me decide on that too) so I was thinking I could keep regular tabling (Another favorite) directly under the MH and smooth skin across near the edges and lower, sound good?
I will have a low profile scape, minimalist and probably 2 islands.

 

Anyone?

 

You don't have to hammer them with light.I have a few A. echinata and they are almost at the bottom.They encrusted and are colored up and are growing.I have 2 x 250 20k xm's and 8 T5's for light,tank 20 inches deep.And i have a few tablers only 12 inches from the halides getting blasted by light,and loving it.

 

Use the following link Corals of the World - Photos, maps and information about corals and reefs it has the depths of some of the deepwaters and where the are collected. Some deepwater really aren't deepwaters at all but just a reference to their smooth skin. Be careful about dipping deepwaters as many dips can do much more harm than a thorough inspection.

 

Thanks for that man! I'll be getting some suharsonoi frags when you get them back in!

 

Could I feasibly use basically a 20K halide or full blue LED?

 

I think so on the halide. Not enough spectrum with the blue LED. I would add in some white to the LED.

 

What would I be looking at PAR wise for the true deepwater corals? Like 70ish?
