Some suggestions please.

I got my MH lighting coming in today and I want to move the SPS Corals where they benefit the most from the light and current, looking the tank over and having a hard time finding new spots I seen all the wasted space in my tank, in center behind the macro algae their is to much empty space and to the left there is a cave, that cave is bigger than you may think from the pic, wasted space for more Corals and its so hard to find places to put those animals that are on those darn frag plugs, the only way I am even going to think about making more space is by breaking up that big rock on top of the cave. I really don't want to break it, but with its size if anything is going to be rearranged, its going to have to be broke up, that right side is fine.

 

I think you have plenty of space for frags of sps. But obviously you seem not happy with your scape. I have redone mine 3 times, and the 3rd time was a charm. It's not fun, but when you finish, it's like you have a whole new tank to look at.

 

I'm sure! but only the left half of the tank will be touched, I wanted caves to put Corals in that don't like the bright light, that cave on the left is much bigger than I need and the rock is so big, thin and long, really does limit what I can do on that side, here is another problem, the guy in the pic became fond of this flat rock, I take the rock out and smash it, I smash it with him on it.
That big flat rock got some nice holes in it that would be perfect for this plugs, but the angle is all off as it sits and I can't use them, if i break it up and then can angle the holes so any plug i put in it will sit up straight.
Yes I am trying to convince myself to just break it and redo it, hahaha!
