For Hans Grander, the most important instrument to study the element water and its behaviour is the microscope. Hundreds of water samples from all parts of the world (the Nile, Po, Ganges and many other rivers and sources) can be found in his "make-shift lab" and have been studied by him under the microscope in order to determine how different waters of the earth actually behave.
If a burdened, contaminated water was treated with his process, it began to regenerate itself. It regained its vitality. The useful micro-organisms were able to unfold and become active.
