+1 on that. dropping it to 1.015 won't affect the fish (not the same for corals) but raising it must be done very very slowy, no more than 0.003 per day as it could kill the fish.
I went from 1.09 to 1.024 in 5 days and all my fish were fine. 0.003 per day.
For the corals though, I would try to get things back to normal faster than a week.
