Aquapapa Bio Sponge Filter for Up to 20 Gal Aquarium (Small 4-Pack)

Sponge filters are a great choice for aquariums of any size, as they provide both mechanical and biological filtration. These filters are suitable for use in both freshwater and saltwater tanks, making them a versatile option.

The Bio Sponge filter is an excellent filtration system that effectively combines mechanical and biological filtration. The air infusion chamber within the filter produces a multitude of tiny bubbles, which promote gas exchange and increase the dissolved oxygen levels in the tank water.

Setting up these sponge filters is a straightforward process. Simply connect the unit to an air pump using the airline tubing (air pump and airline tubing not included). This ease of installation makes them a convenient choice for aquarium owners.

One of the key benefits of these sponge filters is their safety for small fish species, such as dwarf cichlids, guppies, and killifish, as they do not trap fry. This makes them suitable for use as breeding filters or as secondary filters in an aquarium. Additionally, they can be employed as a pre-filtration unit, fitted to an external or top-mounted filter.

The filter dimensions are 3.0"D x 6.5"H, and the recommended tank size for this filter is up to 20 gallons. The package includes a set of 4 sponge filters, providing aquarium owners with a convenient and reliable filtration solution.

In conclusion, sponge filters are an excellent choice for aquarium owners looking for a versatile and effective filtration system. With their ability to provide both mechanical and biological filtration, as well as their safety for small fish species, these filters offer a reliable and user-friendly solution for maintaining a healthy aquarium environment.
