I have a Silverpuppy CS generator and made my first batch. The taste however is a bit metalic (which is OK since my bought CS tasted also a bit metalic) but the aftertase is bitter which I never had when I bought CS here in the Netherlands. I've used pure distilled water form the pharmacys and it took about 4 hours (more or less ) to make the CS. I've filtered the CS with a coffee filter because of the black silver oxide on the electrodes.
My question is this first batch a good one because of the bitter taste or is it somehow contaminated?
