How are you mixing your water? Most salt mixes come with directions - 1/2 cup of salt to a gallon of any fresh water will yield a salinity of around 31 ppt... right smack dab in the centre of the acceptable parameters. Don't ever put concentrated salt directly into the aquarium... only fully dissolved prepared water... the dissolving action can burn a fish's gills, and inverts won't tolerate it at all. I know this may be a simple basic thing, but I cannot believe how many people think it's OK to dissolve a cup of salt in a quart of water and dump it in, or worse shovel salt directly out of a bucket into an inhabited tank!
When I want to bump my salinity I typically just use salt water for a few days as my evaporation make up water instead of fresh... this makes it happen steadily and slowly so as to not stress anyone. If you wish to accelerate it a bit maybe just use hypersaline water at >40ppt as long as it's dripped... again, dissolving is all about ion exchange with positive and negative charges flying around everywhere and your creatures being bombarded and burned... once everything is dissolved it then exists as the delicate ionically balanced environment in which they live...
