Hot RO water

[Alenyc22]

I have a Automatic Water Changing station that I set up in my garage. Currently one container is holding RO water and the other has salt (I'll include a picture). The RO container is also my auto top off reservoir. The temp of the saltwater and RO are roughly around 90 degrees because I have this in my garage and I'm in sunny Florida. I have a couple questions regarding this. Mind you my display tank is 92 gallons. It's a redsea 450

1. Does the temp of the water affect the salinity?

2. Will the temp of the water affect the mag, cal, and alk?

3. Since it's only a 20 degree difference and it's pumping water in a little at a time, if the top 2 are ok then the water going in should be ok. Right?

It's only 10 degrees above the temp recommended for reef. But let it cool down before putting it in the tank. A temp above 83 degrees can start coral bleaching in real short order under strong lighting. And hot water is REAL oxygen short, which affects your fish. I don't think your readings are going to be that off.
