I test before and after every water change, and whenever anything is looking out of wack

SG is important because it is a measure of the concentration of salt in your tank water.

No, that would be correct. your specific gravity is 1.025. Specific gravity does not have units. It is a ratio of pure water to (in this case) saltwater concentration.

According to info on the internet, natrual seawater in a reef varies from 1.025-1.027.
