Product Information: Water Butt Treatment from Defenders is a safe, non-toxic treatment to clean domestic water butts that collect rain and household water (baths, washing machines, sink, etc.) It uses natural technology and is safe to use in all garden situations. It treats up to 6500 litres of rainwater and household water, eliminating unpleasant smells. Following treatment it prevents green water and soap scum, keeping stored water free from algae and slime. This treated water is safe for watering garden plants, flowerbeds, and lawns. To treat rainwater in a standard 100 litres household water butt, dilute 25ml (three capfuls) in a clean watering can then pour into water butt; add a further 25ml weekly between March and October, fortnightly between November and February.

    If only we had rain to fill our water butts!
    I was going to say, everyone's must be empty by now so perhaps do what I did and take the chance to rinse it out.
    Should be some good fertiliser at the bottom for the plants! (edited)

    Never knew we had to treat rainwater
    The standing water gets a bit smelly and can host flying insect larvae

    At a rate of 25ml per 100 litres every week you'd go through this stuff in no time.
    I'm sure bleach can be used safely in the right quantity to achieve the same effect as suggested on various sites about collecting & re-using your grey water.
