Makes it easy to monitor the pH value in fresh and marine water and ponds. For approx. 100 measurements. In case of too low pH values we recommend sera KH/pH-plus (in fresh and marine water 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.
