Two days ago I filled a 30 gallon trash can with city water.
Then I waited!
Now the chlorine is out of it so I added about 4 cups of molassas.
And a shovel full of composted rabbit manure.
When I can I will add 2 bubblers with a cheap air pump. this will keep the water moving and air in the water. Good bacterial love air.
Put the lid back on to keep the skeeters out.
I will stir twice a day.
