Description

The salt content of saltwater can be measured with a measuring cylinder and a hydrometer. Tropic Marin's Measuring Cylinder made of transparent plastic and Hydrometer made of hand-blown glass are precision instruments for determining the salt content in saltwater aquariums. Used in combination, they ensure an accurate measurement of the salinity in your aquarium.

Note: With an average salinity of 35 ‰ at 25 °C, natural seawater has a density of approx. 1.023 kg/L. In a saltwater aquarium, you should aim for a value between 1.022 and 1.024 kg/L.

Instructions for use:

  1. Fill the measuring cylinder with 400 ml saltwater. The water temperature should be around 25 °C.
  2. The hydrometer must be dry and clean!
  3. Submerge the hydrometer in the water and make sure it floats freely.
  4. Read the salt density on the green scale of the hydrometer. Pay attention to the height of the water surface.
  5. Rinse the cylinder with tap or reverse osmosis water to remove any salt residue.

Our expert Oliver Knott recommends:

Most hydrometers are calibrated for use at 25 °C. Therefore, make sure that the aquarium water to be measured is at 25 °C. Otherwise the precision instruments will not show the accurate salt content.
