Curious??? I have a fish pond in the backyard and during dry spells, I have to top off the water. I have "city" water and they do treat it with Chlorine or chloramine. When I add the water, I add a water conditioner that neutralizes chlorine and breaks the bond between chlorine & ammonia (chloramine). The ingredients in this stuff are:
Sodium Hydroxymethane Sulfinate, Polyvinyl Pyrollidones, Organic Hydrocolloids, Organic Chelating Compoinds.
Any chemical gurus out there know if this would have adverse effects on the beer and/or yeast? I don't know the concentrations of the ingredients, but it only calls for 5mL to every 10 gallons.
