salinity increase

[subman]

So in blind joy setting up my new tank I made a newb mistake and didn't recheck my salinity levels. I filled the tank set the salinity to 1.025 and then proceded to add rock, re did plumbing 6 times ect. Then when I thought things looked good I moved the fish over and then the inverts. Well I had massive invert die off. Rechecked the salinity and it was 1.010 Im guessing that over the time setting things up I removed a bunch of water and replaced it with fresh bringing it down so low. So I have been raising it slowly over the last 3 weeks and its now up to 1.019 but Im wondering if I could do it any faster to finish it off. I am trying to get the tank stabilized before holiday season comes and this is the last parameter before I start setting my doser.
any recomendations as to safe speeds increasing the salinity?
