I have a 55 gallon QT running right now and I am ready tobegin raising the salinity back up to normal. My question is though.... I will be adding water with a 5 gallon bucket, so how high should the salinity be in the bucket each time I add the water in? I am not sure about this and couldn't find aynthing that clarified. Thanks

Mix it to display tank levels (1.025-1.026.)
In a 55, I'd add a gallon at a time, wait an hour then measure. Repeat as needed.

No. Fish can not tolerate a rapid rise in salinity. Raise it back over the course of 5-7 days.

If you're at hyposaline levels (1.009 or 14 ppt salinity), and you need to raise it to 36 ppt salinity, you're coming up 22 ppt over 7 days, so 3 ppt a day.
You can do small water changes 3 times a day to raise it 1 ppt each time. It's important to measure after each water change out. What are you using to measure the salinity?

Good deal. You should be fine. Measure actual salinity as opposed to the specific gravity.
