Alveopora help

[tony727]

I have an alveopora (I think) I'll post a picture of it tomorrow.
I'm not sure if its happy or not because it doesn't fully extend all the way.
Sometimes it extends pretty long but at times its almost closed up.

I've tried feeding it from cyclopeeze to reefroids, but I don't see a reaction.
I have it placed in the middle of the tank.

Params
1.026 salinity
10.5 dKH
430 calcium
1300 mag

The thing I'm worried about is my nitrates are high at 20 ppm, but its slowly dropping. Its high because this was an old tank that just got revived.

This is how it is, most of the time. Sometimes its open more.

I can't see a pic if it's posted.

Probably has to do with it's placement -- doesn't like the light/flow, or something is constantly bothering it
