Abstract
Abstract A method for detoxifying ammonia in an ammonia-containing aquatic system comprises adding to the system a novel composition comprising an amine-based ammonia detoxifying solution in an amount effective to detoxifying substantially all of the ammonia, where the solution is non-toxic and has a pH suitable for aquatic life. Further, a method for detoxifying contaminants selected from the group consisting of ammonia, chlorine and chloramine from a contaminated aquatic system comprises adding to the system a novel composition contaminant according to the present detoxifying solution in an amount effective to detoxifying the contaminants, the solution comprising an amine-based ammonia detoxifying compound and a dechlorinator, where the solution is stable, non-toxic and has a pH suitable for aquatic life. In addition, methods for preparing the ammonia detoxifying and contaminant detoxifying compositions and the compositions produced thereby are disclosed.
