Hello. Sorry to hear of your problems. If you can follow this link and fill out the questionnaire and past it back her it will save a lot of questions and answers. Hopefully we can get to the bottom of this... The first two issues I see are ammonia (not normal) and water change routine, but the other questions are important as well.
