You can acclimate fish to a salinity of 14ppt (not SG) quickly provided the temperature and pH are in line. Not usually a good idea to combine hypo with copper. Not much use for methylene blue and it will kill the biofilter. Go slow when raising the salinity again. Take about a week.

thanks for the reply.i only can measure sp gr .what is this in ppm.

The specific gravity varies with temperature and most hydrometers (especially plastic swing-arm) are too inaccurate. Best guess is a Specific Gavity of 1.009, assuming you have a tool that will measure it correctly. Look at the water level if you use a hydrometer that floats in the water and not how high the water climbs the neck of the hydrometer.
