Fishless cycling is a form of "maturing" an aquarium. In this process, ammonia is provided to allow beneficial bacteria to colonize. Fishless cycling can reduce the chance of fish loss resulting from insufficient populations of these bacteria.

How do you do a fishless cycle?

A fishless cycle is the term used to describe the process of growing a colony of 'good bacteria' in your aquarium filter before any fish are introduced to the tank. By adding a source of ammonia you can encourage the growth of the bacteria that process ammonia to nitrite, and nitrite to nitrate.

Is fishless cycling necessary?

It is extremely important for tank owners to cycle their tank properly. High ammonia and nitrite levels can and will kill fish. Fishless cycling provides water adjustments without harming living fish. It is the most humane way cycle aquariums and prepare a tank for use.
