Throughout the U.S., chloramine (a combination of chlorine and ammonia) has been added to the public water systems as a disinfectant. Chloramine will kill the beneficial forms of bacteria in the compost tea. Unlike chlorine, it remains in the water through an aeration process or letting it stand overnight. It must be neutralized by adding a water conditioner.
Since chloramine can be deadly to fish, most fish and pet stores carry water conditioners. One brand is Tetra's AquaSafe. It is labeled to neutralize chlorine, chloramine, ammonia and various other chemicals. Apply per the label, which should say 1 teaspoon per 10 gallons. Using the neutralized water, dilute your compost tea in your pump sprayer.

I know that offgassing of chlorine and ammonia will happen eventually if water is left unagitated, so with the addition of vitamin c or some other material i see no reason why the chloramine wouldnt be seperated and eventually off gas in the form of chlorine and ammonia, it just might take more time using your hands than a highly agitated medium like what you see with motorized aeration.
