I just added a new member to my family and now my ouse is starting to stink due a smelly fish tank. In the tank is a black fin shark, he is in a new tank filled with spring water and a pump running all the time, the tank has a light some small gravel and a few fake plants. The only thing I can think of is he has ick and I have been treating for that but will ick make the tank water stink and either way how do I get ride of the smelly water. The fish has only been in the tank for a few days. Any help would be greatly appreciated. Thank you.
