Tks for reply.

Actually I know that the 4dKH I was able to make was pure luck.
I just poured some distilled, without measuring, and it tested out 4dKH !
Don't know if I'll be able to do it again but, I'll see when I run out of my present supply.

As to the accuracy of my PH test kit, it's Aq. Pharmaceuticals. Is this considered a good test?
