ID please - what is this and how can I improve it?

[ergo]

The coral in the picture is mostly white (it was when I bought it) but a few tips are very faint blue/purple. I'm wondering if it is getting too much light rather than not enough.

I have it under a 8 x 39W ATI powermodule and it is about 4 inches under the surface

Any ideas what this SPS might be?

How I can get it to colour up - my parameters are pretty good so I do not think that water quality is the issue

Thank you!!

Just leave it here it is. It will color up in time. Its stressed out right now, so leave it be.

I believe it is A. suharsonoi

Actually, I would rotate it so the coralites are facing the light.
So basicly 180 degrees. You don't have to, but that looks to be
how it was growing.

I was wrong on the ID. Its Acropora multiacuta. The axial corallites are different. A. soharsonai has them more tapered and pointed than multiacuta (just like the pic above).

it is too close to the light in my opinion, those corals can be at the bottom to middle of the tank, good flow, and do great...

This is an interesting comment.
Mainly because this comes up all the time.
Although you make a good point that they can be placed lower
in the tank, I think the Vast majority of people think this because
it is a Deepwater Acro. The term Deepwater has more to do with
coralite structure than light requirements. In my Experience these
corals look most spectacular when placed in higher light. Many
will develope cool variations of Purples, and Yellows.
I am not saying you are wrong, but if you have one in lower light
frag off a piece and put it under more intense light, you might be
very surprised with the result.
