I recently bought a new hood (http://www.petsmart.com/product/index.jsp?productId=11252590) for my 10 gallon tank. It came with a 15 watt T8 Full Spectrum lamp. Is this okay for the java fern and moss ball I have in the tank, as well as the anubias, java moss, and dwarf sag that I am adding to the tank soon? If not, what kind of light do I need to get?
