Hey well I appreciate the replies, but I to hear from someone who was at the last meeting. And someone who particular attention to what the guest speaker said that she did. It made more sense than using household ammonia. This info is for my friend. Myself I have 36 aquariums up and running, I don't have a problem being able to start another. I know that our guest speaker said she used Fritzime and ammonia choride. I just need to know how much. Thnaks for your help.
