Can a fish tank be cycled in 2 weeks?

How fast can an aquarium cycle?

By keeping only 10 to 20 percent of your total fish load to start, your ammonia and nitrite spikes will not be deadly. Test your levels regularly and get ready to do some extra water changes if your levels creep up too high. In four to six weeks, your tank will be cycled.
