Tank water is often not alkaline; it's typically acidic. Rainwater, which commonly fills tanks, often has a pH below 7, which is considered neutral. A pH below 7 indicates acidity.
However, it's important to note that the alkalinity of tank water can be altered. Specialized filters, such as those offered by Waters Co, can transform acidic tank water into alkaline water with a pH of approximately 7.5-8.5. This process adds vital minerals that are typically lacking in rainwater.
Therefore, whether tank water is alkaline depends on the water source and any treatment it undergoes. Untreated rainwater collected in a tank will usually be acidic, not alkaline.
- Untreated tank water: Typically acidic (pH below 7).
- Treated tank water (with mineralizing filters): Can be alkaline (pH around 7.5-8.5).
The provided reference states: "Rain water and specifically tank water is often acidic (below 7pH which is base neutral) and lacking vital minerals found in spring water supplies. Activating filters such as Waters Co's transform tank water into Alkaline mineral water with a pH level of around 7.5 – 8.5."
