Also there is a product called Cycle that the people at the petstore I go to regularly said to help produce good bacteria. On the front it says:
reduces fish loss, helps keep aquariums healthy, rapidly matures new aquariums, and for either fresh or salt water tanks. Its a product by NUTRAFIN.
The side says:
Cycle releases massive amounts of beneficial bacteria into the aquarium. Each dose works to reduce dangerous ammonia and
nitrite levels in the aquariums. This helps prevent fish loss.
Cycle is an all-natural product that will not harm plants, animals or humans. It is impossible to overdose.
Cycle is super-concentrated. It will initially appear cloudy and may emit a slight odor.
And then after that it tells you how to use it.
