GG3 for soft water -- thus why its used in pure water
GG4 for hard water
ok well lost now as will anyone reading this post changing from trad to wfp.
I myself think i live in a hard water area (do not know as it comes out of the tap and does not say i'm hard) But i live in cambidge and from what i can gather it is a hard water area.
I have been always told gg3 is the best, now i am well confused, what is better for the change over (i am so glad i did not order that a min ago before checking back on here)
gg3 gg4 (is there a gg5?)
many thanks guys
