Hi Folks,
So........................
To sum up what we have learned from this thread................
To keep our pure water safe we should:
1. Try not to let it get warmer than 20 C
2. Keep it in the dark.
3. Keep all our equipment clean.
4 Don't store it too long
Oh.........
and iff us chaps start sniveling and feeling a bit disorientated.....................
Don't worry..............
It's only MAN FLU
David
