4X Bio Sponge Filter for Betta Fry Tank Up to 15 Gal

The sponge filter is an excellent choice for aquariums as it offers both mechanical and biological filtration. Its unique air infusion chamber generates a multitude of tiny bubbles, facilitating gas exchange and enhancing the dissolved oxygen levels in the aquarium water.

To use the filter, simply connect an airline to the unit, which allows it to provide efficient aeration alongside filtration for your fish. The sponge material effectively captures larger waste particles, helping to keep the water clean while ensuring that fry remain unharmed, as the filter does not trap baby fish.

In terms of size, the filter measures 3.5 inches in width, 1.8 inches in depth, and 5.5 inches in height. The sponge itself has a diameter of 1.8 inches and a height of 3.12 inches. These filters are versatile and can serve multiple purposes; they can be used as breeding filters, secondary filters, or even as pre-filtration units when attached to an external or top filter.

Each sponge filter is suitable for tanks of up to 15 gallons, providing adequate filtration for smaller aquariums. The package includes four sponge filters, conveniently packaged in a poly bag, ensuring that you have enough filtration units for your needs.

Overall, the sponge filter is a highly beneficial addition to any aquarium setup, ensuring a clean and well-oxygenated environment for your aquatic life.
