I see more color from the corals in the first pic-like the gsp and some shrooms-the Monti does look brighter in second pic but could that be cause it's closer to the lights then the other corals?

There are a few reasons for this:
1. By the time I got the LEDs hung, the halides had been off for about an hour, then when I pulled the fixture down I had to turn the T5's off as well so the corals were well into their typical nighttime routine.
2. The pendants aren't positioned / configured how I want them. Once I lift them off the water a little more and position them to be more centered on each respective side of the tank the spread of light up the sides should be slightly better.. right now both pendants are too close to the center so the sides are lacking light.
Im going to re-hang them tonight, supported by turnbuckles from eye hooks in some 2x4's across the floor joists above. Im also ordering some roller track and rollers (right now in another tab) to hang them from McMaster-Carr.
The monti looks brighter because the light is simply brighter.. I wish I had an apogee to do some tests, but visually you can see how much brighter it is in person.
So I decided that since I had my slide rails already ordered it would be silly to re-hang both pendants so I just re-hung the one on the right for purposes of spread testing and color temp adjustment.
nothing exciting about eye bolts and turnbuckles so I didn't take any pics, especially since I will be switching it up in a few days.
First: a word of advice. Be careful if you're adjusting the pots inside of a meanwell driver to set maximum light output. The heat sink by the pots is safe, but the other one is not... as seen below.
Yellow tang and blue throat trigger hanging out near the front glass. the bottom rightmost rock in this pic is actually almost touching the right panel of glass and about 2" off the front glass, maybe less.. but you can see how much light is still on something in that far of a corner.
and here's how it looks as a full tank. remember, the left side is still not properly hung, you can tell by how defined the shadow is from the center brace on the left, whereas on the right it is much more hazy.
I took some macro shots of the frag rack but nothing turned out quite right. but the corals are adjusting nicely it seems.. The poreites(sp) and some purple/blue acro i got from kee's in particular have significantly more polyp extension compared to under halides.
Im fairly pleased with the color temp I came up with.. but that's personal preference... in any case It's better than the super-purple hue I had yesterday
