Nice tank. I think it could be improved by shipping me some of those really "ugly" zoos (jk)
I have both PC & T-5 lighting. I use t-5s to supplement the blue spectrum (actinic & 20000k). I would probably switch your actinic or 50/50 PC bulbs for pure 10000k & add some blue t-5s. That would make the tank more coral friendly & make better use of the lighting you do have. Going all t-5 is expensive & the bulbs do not have a very long useful life, so I wouldn't recommend a pure t-5 switchover.
JMO & E,
