This is a Pre Seeded Sponge filter smal (or active sponge filter) This is the small-sized filter and is designed for moderately stocked tanks up to 20 gallons.

This filter requires the use of an air pump to be attached using airline tubing (not included) It has been in an aquarium for at least 6 weeks to be pre-seeded with nitrifying bacteria to help jump start your cycle or even instant cycle your fish tank as seen in this video How to Instant Cycle a Fish Tank.

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.

This filter can be shipped in a box with only 2 other items (2 different strains of fish as an example) Additional shipping charges may apply when I try to fit everything in the order. I will email you before shipping if an additional charge will be applied.

Please the pictures for the actual size. The water bottle is there for reference size. This is the size filter you will receive. The actual filter may differ slightly depending on stock availability.
