rain water
Hi,
the KH (12) & GH (14) of my tap water are to high, I looked at reserve
osmose equipment but this looks like an expensive methode - not to
mention the waste of water (only 1/4 ratio)
what about just using rain water (collected via the roof of the house &
stored in a 7000 l concrete 'barrel')
I live in Europe, Brussels, and am worried about pollution.
rain water :
PH : 7.8
GH : 3
KH : 2 (I would have expected lower)
would it be sufficient to run that rain water trough a activated carbon
filter before use ? Buying water at the local shop is not an option due
to the size (700l) of my tank.
any help is appreciated.
