Hi all.

I've been lurking here for a bit while I'm planning a small (20 gal) densely
planted tank.  The last piece of equipment I need to buy before setting
things up are the lights. Someone recommended power compact flourescents for
their intensity, long life and cool operation.

Question:  Would two 28W Osram 13" power compacts (1 white, 1 blue) be
sufficient light over a 24" x 12" 20 gallon tank?  The next size up (58W)
gets pretty expensive.  Or would I be better off with 2, 3, or 4 regular
flourescent tubes?  The Plants FAQ lighting formula suggests about 930 watt
hours for this size tank.  Can you get away with less wattage by using power
