Makes it easy to monitor the pH value in fresh, marine and pond water.
For approx. 100 measurements.
In case of too low pH values we recommend Sera KH/pH-plus (in freshwater aquariums) or Sera pond bio balance (in ponds), in case of too high values in freshwater aquariums we recommend Sera pH/KH-minus or filtering through Sera super peat.
