pH may be one of the most critical variables of water quality parameters in a healthy aquarium environment.
If it is fixed at a position that is either reading too high or low, it could be harmful to the organisms in your aquarium.
Observed changes can also give you early warning that other water parameters may be endangering the health of your marine aquarium.
By using a test kit to monitor your pH, this will allow you to correct the problem expediently.
The pH should be tested regularly to maintain ideal conditions.
