Mebbid
Aquarium Advice Addict
Its not just mine. Its very common for people to start up a tank without any added bacteria.My opinion is that it does not, and the tank will not cycle. However Mebbid states he gets a cycle. If that is true it is because bacteria is all over everything on earth all the time. The floor, objects, animals, people...everything. IMO it is not the nitrifiers but Mebbid's results seem to show that there are some in there.
It took me like 3 or 4 weeks of i remember correctly.
