Salinity drop

[Aaron88]

So my ATO went a little crazy today and dispensed to much water. My salinity has dropped down to 1.020 I’m gonna do a water change to help bring it up what what should I mix the new waters salinity to.

Is this a fish only tank? Do you have coral?
Tell us more.
If it’s a fish only tank, just bump it to 1.021and leave it there.

I would bump it up to 1.022-23 or so, and a couple days later add enough heavily salted water in a high flow area to raise it to 1.025

Or raise to 1.022 now and put SW in your ATO to slowly bring it up the rest of the way
