Sqasnatch - Try starting the light cycle with actinics coming on an hour before the 10k, then have the 10k on for 8-10 hours, and lastly, have the actinics on for an hour after the 10k have been shut off. Try starting on the lower end of the 8-10 hour range for the 10k, if corals seem to be pale, then you increase the time the 10k are on for another hour, reason for this is that if lights are on too long, you are encouraging algae growth. You may want to get a timer since it will be easier letting the timers cycle the lights than doing it yourself. Don't know about the zoanthids turning brown with too much light, but they can bleach with overly intense light conditions.
aubel07 - Any light is fine for fowlr, with no coral, you don't need super intense light like you would with a reef.
Hope this helps both of you.
