new lights.

Just purchased new lighting for my 20 gal. 65 Watt 10k with 65 watt Actinic and lunar lights. Currently I have FOWLR no coral as of yet. I have the regular stock lights that came with the tank. Do I have to climate the fish to the new and brighter lights, if so what would the timing be?

The fish should do just fine by just a cold-turkey switch.
They'll be more negatively impacted by changing your lighting on/off times than by how bright the lights are.
