CJH0825 said:I was always told, the best way to cycle a tank quickly, is to buy like 15 goldfish and just let them to do the work. goldfish are cheap ( here they are 14 cents a piece ) so if they die, it's not a big deal ( although no one wants to see fish die ) but it is a cheap and quick way yo cycle your tank. That's just what I have been told. It could be right or wrong.
