Need quick help for anyone who's up - salt mix

[Reeftanker3295]

I leave for Ontario tomorrow for two weeks and I wanted to do a water change before I left but I ran into some issues. I only had enough DD H2o salt to get the salinity up to 1.015. That was yesterday. Today I got a bag of Coralife salt and raised the salinity to 1.025. I did that at 9 PM. I plan on doing the water change at around 6 AM, do you guys think it would be fully mixed by then, or am I just asking for trouble?
It's a 145 gallon reef system, 20 gallon water change, and i'm mixing it with a mag 5.

Think should be fine. Lot of people when they change salts mix it that way 1/2 of original and 1/2 of new.

Yup should be okay
