Looking for some information about what kind of light program that is beneficial for the corals.

I got the following:
  • 4x dimmable T5 2x54w (can only be dimmed in pairs of two and two T5 tubes, so I can regulate f)
  • Profilux 3ex
  • Skimmer
  • Alge Scrubber (so I'm not to worried about algea growth in the tank)
  • Assorted corals SPS, LPS and Soft.


I got some questions about which features to use, why and how much. My goal is to maximize the coral growth.

  • How many minutes should I use on sun rise / set?
  • How many hours per day should I run with full light?
  • Should there be a set reduction of light at any time during the day, for instance a dip in output from 100%-80% between 1 pm to 3 pm? If yes how much reduction and for how long, and why is this important?
  • Should I use the cloud functionality? How large probability, how much reduction?
  • Should I use rainyday? How many? How much reduction?
  • Should I use thunderstorms? Are they usefull for anything other than showing off to friends?
