water from rain barrel smells
We have 3 interconnected rain barrels collecting rain off the roof. They are light grey in color and are made of heavy duty plastic. (formerly pickle barrels, apparently) Sometimes the water we draw from them will have a very rank smell. I could understand this if the water was sitting for awhile, but this week it was 2 days after the rain collected there, and the barrels were empty before that. The temperature was around 60 degrees at that time and they are protected from the sun a little, with latice.
Does anyone know if there is something we can put in the barrels that is safe for plants to prevent this?
