Salinity

Need a place in your tank that tells you it’s Full, a mark of some kind.
Every day, add fresh water to that mark to make up for evaporation.
 
I'm using red sea coral pro plus salt it has a max mix time of 2 hours and some other stuff your not supposed to do or it will cloud and precipitate trace elements out. Other salts take 24 hours to mix....Some take around 5 hours, have to read the instructions and follow them for sure...

The levels in the sump read 1.026, there is a black mesh line on the top of the tank but I always fill it over that, maybe I should put a mark on there somewhere.

I also have the red sea coral pro

If you have a sump, evaporation will only be visible in the chamber where your return pump is located. Put your mark there and add water to that chamber.

This calculator may assist you in altering salinity if needed.
 
Here’s a pic of mine. The area where the return is small. So I need to top off 2 times a day in summer. I use that partition at the end where the pump is to judge Full.

it looks like I’m low a little bit!
What do you have in your tank ? How long Been setup? Hope that helps your question!
 
I use the simple formula below. If you have 13.5g total of 1.027 water and you want to do a 50% water change to get it back down to 1.024 you would put in 6.75g of 1.021 salinity. I've attached a simple calculator in excel as well.

13.5g (1.024) = (Wg added water) * (X Salinity) + (Yg remaining water) * (Z salinity)
W, X, Y, and Z are variables.

However, as others have said, don't do a huge water change and a fast salinity change. Go slowly to get it back to where it needs to be.
