Light bulbs

[donaldgoof]

For a ten gallon I currently have two strip flouresent lights, one blue, one white. Both are 15W strips. They are 18" in lenth and I would like to incease wattage for the tank. Does anyone know of 18" bulbs that are of greater wattage than 15W? I'm planning on some soft corals and would like a little more oomph for them.

check out the auction site. I personally do not know!

I was also wondering (as I'm new to the hobby) if the blue light is to be left on all the time or if I can turn the lights all off at night.
