I'm sorry if it seems like we are all harping on you. Some of us have been doing this for a very long time( I've had tanks for 42 years). I don't claim to be an expert, but I choose to be here and help people with their problems, if I can. We are not like the lfs. We gain nothing by giving you advice, except the satisfaction of seeing our hobby grow. You are very welcome here. We will help you all we can. But in order to help, we need you to start listening to us. Some people are very lucky and can do everything wrong and come out with great results, but that's just luck and luck eventually runs out. Once again, we have NOTHING to gain, just the happiness and health of YOUR fish.
