How do you neutralise tank water?

To neutralize tank water, you first need to test its pH level using a pH test kit. If the water is too acidic (low pH), you can add a base like sodium bicarbonate (baking soda) or lime to raise the pH. Conversely, if the water is too alkaline (high pH), you can add an acid such as muriatic acid or vinegar to lower the pH. Always add chemicals gradually and retest the water frequently to avoid drastic changes.
