If you wouldn't mind, could you please elaborate on reef tanks not being successful under PC? Are you talking about long term success for larger tanks? Nanos are typically 20 gallons or less right?
Most soft corals can be kept under PC lights. But even most nano reefers upgrade their lights to a single metal halide. If you wish to keep LPS, SPS, or anemones then T5s or MH is a must. With how far technology has come over the last few years, the best T5 HO lights are on par with MH. Using thinner bulbs and individual reflectors, T5 HOs are now putting out more lumens, less heat, and using less energy than MHs. However, MHs penetrate deeper and have a wider spread than T5s. T5 fixtures AND replacement bulbs tend to be cheaper. PC fixtures are cheap when you buy them, but get ready for a shock when you need to replace the bulbs!
