From my understanding salinity of 14-15ppt is the proper treatment range. This is above the internal salinity for boney reef fish so you are not hurting the fish.
Sharks and Rays are a different story.
As for what specific gravity you will need to find a chart and convert from 14ppt for your temp.
At 1.019 you have not cured the fish of cryptocaryon. They still have it, maybe just at a subclinical level.
