No, you just haven't added enough salt. Make sure it is well mixed each bit you add. It is generally a good idea to add it a cup at a time, mix it, and then check the specific gravity. It takes a bit of time, but if you keep adding salt and checking, you will notice a change until you reach your desired specific gravity. 30g, while small for SW tanks, is still a lot of water and takes a lot of salt to change the specific gravity.
