Unless there is nothing in your tank you don't want to add just salt. I have added a solution of a little stronger salt water but you never want to do it too fast or you can harm your inhabitants. With more salt your ph should rise as well. When my sg was low so was my ph. Now its right on the money.
Tonight I added 3 nass, 4 cerith, 3 turbos, and a cleaner shrimp. Hopefully they get to work on the tank. The cleaner and damsel were flirting and hopefully will hook up so I can see Jaques in action. Took my chaeto out of the cup today and set the chamber light on a different timer than my regular lights. Also redirected some flow with the koralias. I think vermetid snails are causing the spider web stuff so I'm going to look into those to figure out proper action. All levels are good except for phosphate is a tad high. If it is still high in two weeks I may opt for some phosban, not sure yet.
