Ok now after 50 different ways I have decided my one tiny brain cell that I have left ( I did love the 70's ) can not compute.

What would be a very simple / straight up not rocket science, herring brine. Oh yes for fresh water. ( GH )

I have tried several but just can not seem to get comfy with them so I am confessing, leaving myself open to ridicule ( KK may be lurking about ) but the way I see it others must go through this thing. Got to be one that I can use and abuse with out feeling guilt.!
