So, I'm considering making my 20 gallon long into a reef tank. How many watts of T5 do I need? I've seen up to 96 watts all the way down to 48 watts. please help on this.

Depends on what type of animals are you planning for your reef...
(soft corals only? or sps? tridacnas? anemone? etc., etc.) you need to match the requirements of the animals you intend to keep. Two areas you need to understand are spectrum and intensity... your research will lead to success, here are a couple of links that will help you...

liveinabox,

You may need to be even more specific about your question. a nano reef could be mixed, all softies, LPS only, possibly SPS. However, if this is your first reef tank, you may be disappointed with such a small setup if you fail or even succeed and wish to upgrade.
