You have quite a bit of light there. 50 years ago I got my first 5 gal and shortly after two 10 gal tanks. It was easy then, because we did not have bright lights. Algae was pretty rare, and never aggressive like it is in hi tech systems. If you really want that much light, you will probably need either CO2 or Flourish Excel or its equivalent. Assuming you have plants, you will need ferts to support your lights, or once again you will have an algae farm. You should be fine if you research these topics some.
