Agreed it's a bit high. Just bring it down slowly and you'll be fine
And IMHO 27.8c (82f) is a bit high as well, but that's just me

Did you test your WC parameters before doing the WC ?
It's always best to check before tossing the new water into your DT

I always like to have my SG matching perfectly, and my temp very close, before dumping it in

Beyond that, I like to keep an eye on my big 3 in case it'll upset my corals

What kind of water are you using to make your new salt water (NSW)?
Tap ? RO ? RODI ?

What are you mixing it in, and if you're using a powerhead and/or heater in the container, are they intact ?

I lost a bunch of fish to salinity. My tester broke and went from 1.024 to 1.029. Pretty much killed everything in my tank. Even after I caught it. Start taking out a cup at a time of water. Depending on size, and replace it with a cup of fresh. Slow enough to not shock them further but not to long as they are in Super salty water.
