Specific gravity (SG) measures salt content in the water and is only regularly measured in saltwater or brackish aquariums. To lower the SG, remove some water and replace it with treated water that contains no added salt. It increase the SG remove a little water, desolve salt in it and add it back to the tank. WIthout knowing your tank size, current SG and target SG that's as detailed as possible.

I am going to assume that it is a saltwater aquarium. If that is the case, then you either add salt to raise it or remove water and add fresh unsalted water to lower it.
Ocean water is 1.025 on the scale and freshwater is 1.000. Brackish water is 1.012. Testers for specific gravity are cheap, around $8-10 at the lfs (local fish store).
Why do you need to adjust it? Email me if you have more questions. I am not a saltwater expert, but I have some knowledge.

The question makes no sense. The specific gravity of the water? Is it a saltwater, brackish, or freshwater tank? For what purpose? Why do you think you need to? The obvious answer is to increase it you throw more salt, calcium, and what not in. To reduce it you add distilled/RO water.
