Hi Steve, I have had similar experience. I have also used Hach ACS grade calcium carbonate solution, but the sodium hydrogen carbonate seems to work better with less.
Thanks for your data, it goes in the file.

Too-pure produces very low yield. The ideal is probably related to the generator type. Yes I agree. Without come initial conductance, its hard to get the process started. I think that its best to get water as pure as you can and then add a bit of conductivity with baking soda or a previous batch of CS. The amount you add depends on your particular generation method. My generator needs about 3ppm to work quickly (eg, 20min/ batch). So I start with water that is nearly as pure possible. and then add baking soda until I reach 3ppm. >From previous posts and other reading its seems clear that a very small amount of contaminant (eg, chlorides, etc) can have a great influence on the end product. For instance, if I start with .5uS water and dangle my fingers in the jar, it will add enough body salt to wreck the batch (by my standards). Same thing if I don't carefully wipe the electrodes with a clean cloth and rinse the batch jar with distilled water.
