Salinity Test

Testing salinity in a reef aquarium is essential for maintaining an environment that closely mimics natural seawater, which is critical for the health of marine life. Salinity in reef tanks is typically kept between 1.024 and 1.026 specific gravity. You can measure salinity using a hydrometer or a more precise refractometer. Factors like evaporation can increase salinity, so regular testing helps detect changes early, allowing adjustments through fresh water top-offs or salt mix additions. Maintaining stable salinity promotes the well-being of fish, corals, and invertebrates, supporting a thriving reef ecosystem.
