Hopefully that's 14,000k. Ok..so it's a 175 watt halide. How deep is your tank? All of the corals you have are medium light corals, but can be acclimated to higher light. Depending on the depth of your tank I would say you have moderate lighting, so basically anywhere you would like to put them, depending on flow.
As for the actinic supplement, You could use your T8 fixture for that. Put both fixtures on timers and have the t8 fixture run for the full 10 or 12 hours, or whatever your day is for your reef, then run the halide for 8 to 10 of those hours, so you will get a morning and evening simulation.
