Ok heres the problem. My tap water comes out between 130-140 ppm's not that bad but I thought I would try RO water with my coco grow. This is a new RO 4 stage system and the water comes out at 0 ppm's, but as soon as I add 1 teaspoon of Magical I get a reading of my original tap water ppm's, its at 130-140 again. So, is this thing actually working or is it just masking the ppm's. Should I try a better brand membrane? What do you guys think?
