Hey everyone, can't seem to find a worth while answer on this one, I'm going to have chaeto going into a 10g sump, how much lighting should I get?

I have one of those $5 clip-on lights from Home Depot on my sump, the bulb is one of the energy efficient "swirly" bulbs. The chaeto loves it.

I had 18w (2 9w pc) and it grew like weeds. used the same light over a 10g and again over a 25g sump still grew like weeds.
