Answer 1

Cycling refers to the process of building up a sufficient number of the benefical bacteria in your tank that convert ammonia (from fish waste) in to nitrite and then into nitrate. Two different bacteria, one for each step.

Here's a link that will explain all the details and how to handle the process in your tank:

Answer 2

Cycling is a means of transport, a form of recreation, and a sport. The bicycle carries riders across land, through tunnels, over bridges, or, much less frequently, over ice (icebiking). Cycling involves the riding of bicycles, unicycles, tricycles, quadricycles and other similar human powered vehicles (HPVs).
