He claims that its the only real chemical we have. He was attempting to talk me out of an R/O system for my fish room claiming it would be overkill and too expensive. When I explained to him that a type of fish I was getting into could not have carbon in their water due to it being toxic potentionally to the fish, he countered my concern by saying our water softner acts as a filter its self and any traces of carbon in the water would be filtered out before it ever got to the fish.
The Skeptic in me has a hard time believing this. He seemed to be the type of person with a bias towards his methods and shut down most of my ideas without giving them much consideration. Needless to say, I wanted second and third opinions. So here are my questions (finally, sorry)
