Hi all,
Question about how much salt it takes to lower the freezing point of
water. If one has a swimming pool with about 80 cubic metres of water,
and adds 18 25kg bags of salt (enough for the chlorination machine to
say 'enough is enough'), how much will the freezing point of the water
be affected?

Bit irrelevant now really since we have added another
'hivernage/overwintering' product aswell, but now we have thought of the
question we have to have the answer :-)

TIA
