Just a quick question regarding your heat issue. How long do you have them on for? What is the kelvin rating of the bulb. I have been told that a 10k bulb will put out more heat than a 14k and 20k will be less than both. If this this is true or not I am not sure as I have never looked into this. I run 14k Hamilton or Phoenix bulbs (aquaconnect seem nice but are pricey and the availability isn't as good as the other two). I also have 20k xm and radium bulbs somewhere. I never really checked to see if the 14k's raised the temp when i switched from the 20k's, and its so long ago i cannot even remember when the last time i had a temp swing in my tank.
As I stated I'm not sure if this information that was given to me is proven or just the opinion of the few who gave it, but if someone else might know, maybe that might help a little. Also for photo period i would have your halides on for no more that 6hours at the most. After all they are to mimic the sun at its zenith (just before and just after as well) and the sun isn't always the same for the full day, so 6 hours is really all you need.
Also remember for some odd reason in reef keeping lower temps than needed are often quoted by people when you ask. I would honestly worry about your tank if it rises in the summer, but for now I would say you are ok.
