Yes the Vortex Energiser has been used by many customers to energise and clean up stagnant ponds and lakes. Put the Vortex Energiser in the water near the source (if there is one). To speed up this process, tie a piece of string to the Vortex Energiser and drag it along through the water and then leave it submerged in the water.
Two hours should be sufficient for a pond of approx.15m diameter. For a lake of approx. 300m leave Vortex Energiser at the source for 48 hours.
A lake of several kilometres would benefit from having a Vortex Energiser permanently immersed near its primary source. These are just guidelines, please feel free to experiment. More.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
