G'day magoo,
I understand that chlorine quickly dissipates from water, especially in sun
light and thats why pools need daily top-ups . So if you are worried about
it, just fill a watering can one day and use it the next, then refill it for
the next day. I seem to recall that tap water used for aqariums only needed
to be 'aged' 24 hrs for safe use.

After planting many native plants, grasses and ferns, frogs seem to be
making a comeback to our yard. What I'm wondering is, to what extent is
the
chlorine and whatever else from our tap water (in Canberra) harming them.
From what I understood, it doesn't do them any good, but I give the ferns
etc a quick water regularly and assuming the frogs occasionally get wet
from
it, they seem to be coping with it. At least so far anyway - maybe it's a
cumulative thing?

Thanks for any advice,
Scott.
