I recommend this style of the nitrogen cycle as opposed to a fishless cycle. I find using a Pre Seeded Sponge Filter works 100% of the time and there is no stress on the fish or worry about losing fish.
When you receive this active sponge filter, make sure to add any water in the bag to the tank. Do not worry about it being dirty. It is full of nitrifying bacteria and you do not want to throw this out or siphon it out with a water change until the aquarium is fully established.
Please remember that this pre-seeded sponge filter will only affect Ammonia levels and Nitrite levels. If you have high nitrates, you will need to do water changes to lower it. Please remember to check your source water levels when having water parameter issues.
