The hydrometer measures the density and temperature of the saltwater in your jellyfish tank. The standard reading is 1020 to 1025. It is important to monitor your tank\u2019s parameters to keep everything in balance. If you want to learn more about jellyfish tank parameters, we explain it all in the INFORMATION<\/a> section. <\/p>\n

Just let it float in the tank. The lower scale gives you the temperature, and the upper reading, according to the water level, shows the density of your aquarium. Keep in mind that your tank may suffer from evaporation, so you’ll need to gradually adjust the density. <\/p>\n","protected":false},"excerpt":{"rendered":"
