Good call, Surferjo. This is an often forgotten and important element of tank cycling. A sponge filter is ideal for this. It also provides a large volume in which to grow a healthy nitrifying bacteria colony.
Any tank of any size can be cycled. Any tank 2.5g and up should
be cycled, in my opinion. Even frequent partial water changes will not keep ammonia at 0.0ppm. An established cycled tank can and will.
A cycled tank is not for the convenience of the keeper, but for the health and safety of the fish.
If performing a fish-in cycle, it is highly recommended to have lots of live plants to absorb any ammonia spikes. Floating plants like water sprite, duckweed or wisteria are good. Anacharis and Hornwort a great ammonia sponges. Unfortunately Anubias, Java fern, Java moss, mossballs and other low-light beginner plants are too slow-growing to make much difference in water quality.
