    Default How to store probes?

    I change my set up and now my second aquarium become a refugium in the display tank.

    So, I have some probes (salinity, reedox, conductivity) that I am not using any more.

    How can I store them so I will have them as backup?

    Any special fluid?

    • Salinity and conductivity probes are the same or similar and can be stored dry
      (Platinum or Graphite electrodes to measure resistance; no filling)
    • ph and Redox should be stored in 1-molar KCL solution
      (it´s always a good idea to store the cap of probes; glass probes, filled with KCL)

    Thnaks Wirus!

    Will clean my Salinity & conductivity and store them away.

    What is 1-molar KCL solution?
    Should I go to a drug store to make one for me?

    What is 1-molar KCL solution?
    Sorry, description was not really correct, chemical formula is KCl, better known as potassium chloride

    Translation from german Wikipedia (english article don´t have that note):

    Elektrolyte- und store solution for ph- and redox probes (nearly saturated solution with 3 mol/l KCl solution). Due the identical ionic mobility of potassium- and cloride ions this solution has no electric (chemical; galvanic) potential.
    Your dealer of probes also should have that solution.

    Additional hint: They also should have a Pepsin solution for cleaning the probes.
