I've put a cupfull of 5% sodium hypochlorite bleach in to 220 litres of greywater which I intend to use for watering my garden. It was starting to smell & grow some strange white mucusy substance (bacteria?) because it has been stagnating in a covered water butt outside for several weeks!! (the drought never materialized).
I want to know very roughly how long I should wait before it is safe to use it to water plants - not that I'll ever need to, it's ended up being the wettest summer I can remember.
a day, a week, a month?
