John,
I agree about the lights. It's kind of an experiment at this point. I have more pendants and ballasts ready to go, I just want to see if i really need them. I have seen quite a few German tanks run with all T5s or with combos of T5s and DE MHs. That's kind of where I wanted to go with this system. Those guys apparently keep SPS with these set ups so we'll see.
The T5s are overdriven to 80w each on Icecap ballasts. It seems quite bright to me even with only the T5s running. I've got the light rack mounted with sunlifts so i can raise or lower the lights to any height I want. Right now they are 5 to 6 inches off the water. The few corals i do have in the system now have been under Phoenix 14Ks for the past few months in my holding system. It seems like they've colored up a bit since I put them under the T5s. Is it the lights? I don't know. I guess time will tell.
