The occasional watering hasn't done my yard frogs any harm, but NEVER
use hose water in their ponds. Fill a few buckets and store it for a
couple of days.

In any case, in ponds we really need to start using fish which will deal
with mozzy larvae, but leave (some of) the newly hatched taddies alone.
Only aged water will not kill these fishies. (Make sure they're from Oz
and not a dreaded imported species.)
