Sera pH Test Kit Test for pH
For approx. 100 measurements – tests.
Makes it easy to monitor the pH value in fresh and marine water and ponds. For approx. 100 measurements.
Make sure the carbonate hardness is at least 5°dKH as to achieve a stable pH value.
Otherwise, there is danger of varying (suddenly sinking!) pH value.
Therefore, always check the carbonate hardness by means of the sera kH-Test before adjusting the pH value.
