lighting question?

[cyber_ecco]

Just a quick question for you guys. I'm setting up a smaller reef tank (30g) and I was wondering if I use a 150W HQI MH pendant with a 14000k bulb, do I still need to use actinic lamps? I was hoping to just use the pendant and get some moonlights. If Actinics are needed then I have to go with the aqualight fixture with PC bulbs as well as one Mh, but its so much more expensive. I want to be able to keep some clams, anenomes and soft corals. Tank is 30" long, 12" wide and 20" tall. Thanks.
