Hi, I'm new to your forums and I'm just not sure where else to turn!
We have a 55 gallon freshwater tank. We kept 4 goldfish in it until we transferred them to our outdoor pond. We then cleaned out the tank and added some freshwater tropical fish. About a month ago after doing a cleaning and water change, we had a hydrogen sulfide problem and it killed all but 3 of our fish. Since then we haven't been brave enough to add any more fish. 3 days ago after a water change we again had a hydrogen sulfide problem and it killed another fish. My husband wants to completely give up and get rid of the tank. Any suggestions? What are we doing wrong? I don't want to kill any more fish or deal with the HS smell! Yuck!!!
