Your salinity is a little high, try to aim for 1.025 - 1.026 for optimum levels. Top up with plain RO water to get it down a little.

The pH measurement is probably an error, unless you overdosed limewater. 99.9% of high pH problems, in the absence of limewater overdose, are really measurement errors.
How did you measure it? Do you really mean 0.026 ppm ammonia? Is that total or free ammonia? If total, that's not really enough to worry about, and the value may also be kit error. The specific gravity is a tad on the high side, but is unlikely to be the polyp problem. I'd recommend bring it down to match the ocean, as 1.026 - 1.027.

Wait.
Ammonia is 0.26 ppm (too high) or 0.026 ppm (not too high). The kit will say whether it is free or total ammonia (if not, assume it is total ammonia). I expect the pH testing is in error.

How old is the tank? Ammonia is rarely a real issue in an established tank unless something big is dead.
If it is real, and the tank is not new, I'd look for the cause. You can treat with something like Amquel if you believe it is real and a temporary problem. This may help: Ammonia and the Reef Aquarium http://reefkeeping.com/issues/2007-02/rhf/index.php
