You're fine. Question is -- do the fish and corals look stressed?
Borrow a refractometer and "calibrate" your refractometer to learn how far off it is. I would not make any drastic changes until you do this -- your hydrometer may be inaccurate.
If anything, drop the salinity to 1.027 which puts you in more of a safe range. You can make adjustments when you have real figures to go off of.

IF that reading is accurate, I think all your fish would probably be dead or dying.
They start to look like they are breathing real fast. I would get a refractometer as I too have found reading from the hydrometers are way off. You could try measuring water with the one you have and if it is reading off still, just apply the same correction when youhave salt water in it. Then i would slowly try and bring it down to 1.023. The key is slowly though because the change can kill stuff too.

That specific gravity -- if accurate -- is within normal seawater range (1.020 - 1.029), although it is at the high end. So if the increase in specific gravity was slow, you would not necessarily see stressed livestock.

Although your salinity is within acceptable range, lowering your salinity would less stressful for your fish. When the salinity is high, it takes more energy for the fish to process the salt...that's why it's always good to lower your salinity when the fish get sick. It allows them to use their energy to fight the sickness.

At one point I had 4 hydrometers and they all read differently. I agree with Nicole, "Borrow a refractometer and "calibrate" your refractometer to learn how far off it is. I would not make any drastic changes until you do this -- your hydrometer may be inaccurate." If you are near Irvine I have a refractometer to check your hydrometer. I also have an old refractometer I would sell for $25.00. It still works great. I am still using it, but I just got a new one.
When I got my 240G the salinity of the water was 1.036 and the fish were fine. But they had gotten used to this over a long period I am guessing. I currently keep my tank at 1.024 to help reduce any possable stress on my fish.
