Does anyone have any suggestions for a simple 4dKH solution? I have come across a number of links but it seems they either require scientific scales for the quantities to be accurate ( which I would rather not spend to come up with the teaspoon or so of actual solution) or they are amped up so that I am not measuring in tenths of a gram....but they are for very large ( it seems) quantities. Any help or suggestions woudl be greatly appreciated.
