Hey, thanks for the input. I agree, 100% pure RO water is not the way to go. That is why I was using 10 – 20% tap water with my RO water. I probably didn’t say that clear enough.
With 10 – 20 % tap water and my tap water at 50 ppm; my chlorides should have been around 5 ppm or more. I was checking the kH, Ca and Mg levels and was sure that everything was at about the right level. When I checked the Cl- level, I was only doing it as a double check (a verification of my premise).
To find nothing was a big surprise!
My feeling is that Cl- is a more critical measure of the level of micronutrient requirements in a low GH/kH environment when you are using a tap water/RO water system.
