In the years of studying the water, we found out a great connection between the water and the sun. The water on our planet changes electromagnetically every single day depending on the position of Earth towards the Sun.
It is not necessary to expose the Aǹalemma to the sunlight but it is recommended. If you live in an area where the sun is abundant expose the Aǹalemma to direct sunlight (not through the window) for a couple of minutes every other week.
