I have been to the local fish store, which I must say keeps emaculate fresh water and salt water tanks, but the staffers often give questionable advice. They told me when I am cycling my tank to not vacuum or do partial water changes for the first month (and that my ammonia may reach 10.0!!!). So, I of course ignored them as they were clearly trying to kill my fish. Anyway, could anybody tell me about where my ammonia should stand for the first few weeks. Right now it is about .50 and I have done about two PWCs in the past two weeks.
