question I posed had nothing to do with a fish system. only what happens in a closed system. tank of pure water. 2.00ppm ammonia added and single dose of prime/safe. but like to take this a bit further per say. I add 1.0ppm ammonia and a single dose of prime. treats up to 2.0ppm ammonia. what happens to the extra ions (salt). do they decay with in 48 hours? and if they do, does ions bound to the ammonia molecules also decay?
