I know the treatment for Corid says to treat 5-7 days. Now if a gallon of treated water lasts 2 days, does that count for both days of treatment? Or do I need to treat a "fresh" gallon every day for them? Just wondering.... Also, how long after treatment starts before I STOP seeing the bloody stools? I mixed 2 teaspoons of Corid with a gallon of water...i believe that is close to 9-10 ml/cc?
