Instead of stresing fish with shutting the lights off, why not go for the GHL ProfiBreeze with fan controller, this will then shift all heat from the lights away from the water surface.

I have 2- 110 cfm fans on the tank that come on at nominal +.2, and a 200 cfm fan on the sump that comes on at nominal +.4. Works good in winter, but with 3- 400w halides it's not going to keep cool with air temperatures above 30. I'm also slowly migrating my MH photo period so they will be off by 3PM.
