Hydrometers
Hydrometers allow the measurement of specific gravity or salinity of your saltwater. Marine and reef aquariums normally have a specific gravity ranging from 1.024 to 1.026 with natural seawater usually at 1.026. Refractometers are super accurate and are recommended for measuring specific gravity of saltwater in reef aquariums.
