Numbers look good.
In my opinion I wouldnt mess with the ph though. Adding things to adjust it is just an easy way to screw up the tank. As long as the ph is stable youre set. Also, if your lights were out when you measured the ph then it is probably higher during the day as it should be.

I have a mix of many different saltwater fish amongst my tanks, but I love my Tangs most of all.
