Pretty much what Zapins said. You not only have a light that is of limited use by aquatic plants, but you also have far too little of it. A 15w T8 bulb like that on a 14G is pretty much no light in terms of growing plants, any plants with any real growth, plus if I read correctly it's two years old.

You should be able to find 6500k screw-in bulbs retail. Look for daylight/natural light most bulbs have the K number on them.
