The bubbles don't do much as long as you are using a refractometer...but most salts take a bit to fully dissolve. I make up 50 gallons at a time and the salinity goes up over the first hour as the salt all goes into solution using a power head to keep it stirred up. I sure suggest going at least 4-6 hours before using it. When adding to the main system, I wait at least an hour before checking the total salinity.

Unless you have absolutely no water movement inside the tank, all the new water should be mixed with the old in a few minutes and the salinity established. The new water doesn't stay seperate from the existing water.

Let your water evaporate without tipping up with RO.

If you don't understand the concept...,, dump a cup of salt in a bucket and fill with water, let's say it's 20ppt, let half the water evaporate that will make it 40ppt.
When the water evaporates the salt stays in the vessel.

When you lose water from evaporation don't add freshwater, add saltwater.

Ok thank you that sounds better and more understandable bc I buy my water I don't have any salt on hand.. Or is marine buffer salt?

No..buffer is not salt. It is used to buffer ph swings. Like a shock absorber. Your KH reading show the amount of buffering your water has.
In reefs, this is commonly added with a calcium supplement when wanting to grow Stoney corals.

Be careful of correcting salinity too fast. Use RO/DI for evaporation. When doing a water change check salinity. If it needs to be raised, use replacement water with a small amount higher or lower salinity as needed. I emphasize tiny amounts. For example, if your tank is showing 1.023 and you want to adjust over a few days to 1.025, make your replacement water (20% or so total volume) go in at 1.024, then 1.025 next time and monitor. Do not throw raw salt in the sump. To lower salinity, you can do the reverse. As said above you can also adjust salinity up by topping off with saltwater and monitoring every time.

Exactly. Bubble dont have much to do with it but the time that it takes to dissolve fully does.
