After a few weeks the whirlpool water has changed colour from blue to greenish, even after adding fresh water. What is the cause and can something be done about it?
A high-energy water usually has a slightly light green colour. The blue colour of tap water is caused by the treatment in the waterworks with chlorine and oxygen. In this respect, it is not a bad thing if the water colour changes to light green. It should just not be a darker, dull green. This usually indicates problems with the water quality.
There is a little trick you can do to change the colour of the water back to a bluish colour: Add about 8 grams of pH-Minus granules to 1,000 litres of water. The bluish colour can then return within a few hours.
