Overnight salinity swing - how fast should I raise salinity?

[Mortgaged Reefs]

So my skimmer went crazy last night and from what I am guesstimating I lost ~5 gal in my 60 gal RS Reefer 250. My ATO kicked on and my salinity dropped down to 20 ppt. I have added salt in a mesh bag and have it back to 30ppt but I am thinking I may be going too fast. My tank is wall to wall SPS and bunch of softies. Surprisingly the only things acting weird is the Hammer coral and Forrest Fire digis. My tank must think it was a monsoon rain storm last night lol. How slowly should I get it back up to 35ppt?

Just my option and I mean “ just” lol …
but I’ve had that happen before and 20ppt is low for corals, what I did was almost exactly as you have done:
raise to “ realistic/ survivable levels fast, …
I’m no biologist but it’s the alk swing that bothers me the most …
If it’s already at 30 then maybe take the leap to 35 a lil slower…
Differing opinion/ options won’t insult me. lol

I do the same. I've messed up some WCs where I dropped it to 25ppt, had things look angry and raised it quick to tolerable and then adjusted back to 35 ppt over a few days.
