Hello everybody! I am very new to this boad. Someone offered me a 55 gal. for free so I decided to get back into having a tank. Still have not made a decision as to what kind of fish I am going to get. I am running a Fluval 404. I currently have one 12" air stone running. Do you think I need more air going? Well just waiting to get a cycle going and I will take it from there. Good-bye for now.
