You should check the salt content of your jellyfish tank during every water exchange. You have to do this according to the size of your tank every week, every two weeks or every month.

length of salt content check: approx. 1 minute

How do I check the salt content with a hydrometer:


  • fill the hydrometer with water of your tank
  • gently shake the air bubbles out of the hydrometer and assure that the salt content is between 30 and 35g/L


Only use sea water, distilled water and osmosis water.
