Yes the Ph is a little high try measuring it when the lights first go on ,then the middle of the photo period and at the end of the photo period and post your results.

Yes so at the end of the photo period the highest Ph ,begining of the photo period lowest Ph.

Well, the light itself doesn't cause an increase in PH. It has to do with the photosynthetic process of the algae in your tank. During the day, it's consuming CO2, thus raising your PH.
Speaking of PH, are you dosing anything? If you're not, I'd question the validity of that measurement. Are you using a test kit or a PH probe? If you are dosing something (like kalkwasser), you'll probably just want to back off a bit and keep the PH under 8.5.
Also, if you plan on keeping stony corals, you'll eventually want to raise your alkalinity a bit. You're OK at the high end, but I shoot for 3.0 - 3.5 meq/L for alkalinity. Of course, you'll also want to supplement a balanced portion of calcium if you start dosing alkalinity. You can read up on it in the Chemistry forum once you get to that point. Otherwise, it sounds like your tank is coming along quite nicely.

If you take away the light there is no photosynthesis (sorry just had to say it )

You're correct. I just wanted to make sure it's understood that the light itself does not affect PH. If you shine a light into a bucket of sterile saltwater, you won't see a change in PH. So, yes, the light plays a big part in the change of PH, but it isn't the direct cause.
