1. Basics
The redox-potential or oxydation/reduction potential (ORP) is an electrical value which is a
parameter for the oxydation and reduction processes in the aquarium.
The redox-potential is of special interest in:
Assessing the quality of salt water in aquaria. The ideal range is between 300 mV and 400 mV.
-
If needed, the range can be increased by injecting Ozone into the protein skimmer. The higher
the value, the higher the percentage of oxydation, the „cleaner" the water is.
The redox-potential is used in denitrifying filters to check the acidity. The ideal values are
-
between -300 mV and -100 mV.
In swimming pools the redox-potential can be used for sterilization by regulating the amount of
-
chlorine added by maintaining +700 mV.
2. Features
Aqua Medic Computers are micro-processor controlled units. They are safe, reliable and meet all
requirements of professional measuring and regulating devices.
The Aqua Medic mV-Computer is supplied with a redox probe and standard solution. The ozonizer
(not included) can be connected to the female side of the main power plug.
