a fish only tank (no live rock, no corals, no fancy inverts) will be just fine with your current lighting.
if it seems dim for fish viewing, you might swap the actinic for another daylight, or a single 50/50 bulb.
A little more light would make coraline algae grow a little faster, if you had live rock...but the current lighting would support coraline.
You only need to worry about 3-5 watts per gallon if you plan to add corals, or something like a clam or anemone.
