hey guys, i upgraded to a 20L today, because my clownfish seemed a little cramped. i have 30 pounds of live sand and about 10 pounds of live rock in there, im going to buy some live rock from somewhere and cycle it in my old 10gal tank to bring the live rock to about 15-20 pounds.

what kind of light and wattage should i think about if i want to have some nice corals, but probably not the hard ones. i like the pc's i have now, but what wattage should i look to achieve?
