Ive been running a reef radiance dm-155 on my 60 cube for quite some time now. Growth and color has been good but always looking to see if it can be improved.

So decided on adding a T5 retrofit with two ATI coral plus and building a floating canopy for it. I'm impressed with the amount of light in the tank now. Just have to wait and see if things change for the better.
Here's the before setup
And new canopy:
