I bought an All-Glass 2X55 Watt PC strip light. It works great and was really inexpensive. I bought it used from this site for about $75. The bulbs last about 1 year and are about $25-30 bucks each. I am also going to use my 30W NO strip light as well. BTW, I have a 30gal also.
That is 140 watts total or 4.6 watts per gallon, which is good enough for most soft corals but not good for hard corals and it would be enough for bubble tips or open brains. Unless you are wanting the hard corals, I am not sure you need 12 watts per gallon. I am new at this, so make sure you get other opinions.
I am very pleased with the lights. I have a "baby" brain that came with some of my live rock and it seems to be growing just fine.
I would also make sure that you wait before getting an anenome. They need to have a mature tank to be able to thrive. So, start slow and have fun!!
