Those things don't work very well if at all. Standard tap water has chemicals which inhibit the function of such machines. Distilled water is psychically inactive. Magnets do a little bit,but they limit the charge potential you can get from your machine.
By far the best results you can get is by including a psychic collector to your machine,such as a pyramid and focus it at the base of the vortex. (pyramids only work when aligned to magnetic north) Then set it up to recycle the water through the system. Next get a mixture of water soluble mineral salts and make a saturated solution to run through your machine. Personally I prefer blue halite or another potassium rich table salt.
After several hours or days, crystallize your salt and preferably melt it to re move any carbon based impurities. This salt will be almost as healing as the substance you get initially from the morning dew sea salt path.
