4 or 6 bulb?

[Cathic]

Setting my 30 up to hold the 75 livestock while i rebuild on the 75. Ordering proper lighting to maintain the corals while this happen. I was wondering whether i should invest into a 4 or 6 bulb fixture. I was leaning towards the 6 bulb since I would be able to turn the 30 into a frag tank or a smaller "all in one" reef tank later. If cost becomes an issue though I was looking at the alternative 4 bulb. Its a 30 bowfront. Suggestions?

I think with a 4 bulb you could run a fine frag tank afterwards, id only consider the 6 if you want to keep nems or clams in there.
