Most systems include a diverter valve to send the first flush from the

to become the neighbourhood mosquito rangler.

Isn't that why people keep fish in their rain-barrels?


If you had fish in your rain tank you would need to plant some
greenery to control the fish waste. Then some snails to control the
greenery,frogs to control the snails and then perhaps some reptiles to
control the frogs. Hey, what do you know! We just invented the good
old fashioned swimming hole!
