"...natural seawater has a specific gravity of around 1.026 or 35 ppt. This is going to be a little lower in warmer waters."
IMO you should keep your tank a little lower than this is you don't have an ATO as evaporation will cause the Sg to rise. So with no ATO and adding top off water manually you may want to go to something like between 1.020 and 1.023 or 27-31 ppt.

Don't want to change it too quickly pal. You are okay at your current level. I think I might do a half gallon a day if you want to bring it down. Then run around 1.025 if you are topping off regularly.
