Tropic Marin High Precision Hydrometer with Measuring Cylinder 500ml fish trap the second generationhe salt content in saltwater is usually measured as specific gravity (also sometimes called relative density) and is one of the most important water parameters. Many tank inhabitants are sensitive to even minor changes of the water conditions. These should therefore be kept as constant as possible in the optimum range for each tank. The specific gravity of natural seawater of 35 (psu) is 1. 026 compared to water measured at 25 C 77 F. Our
