For a 30" deep tank? I have a 30x30x30 117 gallon cube right now with a giesemann infinity T5/MH fixture. 150w 20k Radium and 4 ATI 24" T5's in which 2 are Blue plus and 2 are purple. I want a mixed with SPS in the top half and the bottom being LPS and zoas. Nothing on the sand bed really seems to open up :sad2:

Since you have the light give it a go I have the same light but it is going on a 40 breeder. If the light does not work out you could upgrade the light or maybe trade with someone else. A 250 would be best or a single 400 radium with a nice reflector, thats what I want to do if I change may tank.

It appears you are a bit under gunned for the depth of your tank. But, a simple adjustment here and there could make all the difference. In the end the distance between the bulbs and the low light corals on the sand bed needs some attention. Can you drop the fixture closer to the tank? And can you raise the sand bed in the open visible areas by just adding sand in those areas, or put the corals on rocks. Play with these. If some combination of these don't work then it's time to switch to a more intense fixture.

150 MH sucked on my old 24" deep tank. Ran a 14k bulb and just lack of light.

I think the PAR you get from the 150 MH will be poor on the bottom of the tank. If you don't have the need for high light requiring corals then roll with it and see how it goes.

What about the fact its with 4 T5's? Should I throw in a couple Kessil 160's as "spots". That should improve the par quite a bit

Give it a shot but I wouldn't expect the MH's to add much in a tank of that size. I have a 72 x 36 x 27 and run 3-400 watt MH's.
