You may get better results with the bigger panel, or a smaller tank (using it on a 40 breeder only lights half the tank).
I do get algae growing on the glass closest to the light, but nothing on the plants and it is no worse than the fluorescent lights I have used.
Most of my plants are focused on the center of my 'scape I may
get away with the smaller one.. I may get a bigger one though and try it thanks!
