Water hardness plays a crucial role when it comes to ph and alkalinity levels. Harder water assists your pond in controlling varying ph levels and will prevent heavy metal impurities from killing your fish. In addition, harder water usually breeds higher alkalinity levels that will absorb acidic pond content without changing PH, thus keeping your fish safe.
