Also might want to check with your municipal water supplier to see what type of agent they use. Chlorine will evaporate off if left in a large vessel overnight usually. This can be helped with a simple aeration device (air pump and air stone). The agitation also helps avoid the insect issues. Another type of oxidizer used is called chloramine. The reason it is used by some areas is because it is more stable than chlorine and thus will not evaporate off. The only way to remove it is by use of carbon as already mentioned, or with neutralizing agents such as are used in the aquarium/fish industry. Left to sit overnight, chloramine will not dissipate, with or without aeration.Illegal rain barrels? What'll they think of next? How'd ya like to go to the slammer on that one?That's gotta be a joke right?
