Small Aquarium Bio Sponge Filter for Fry, Betta, Shrimp in 2-5 Gallon Tanks

Focusing on aquarium supplies, hygger continues to provide functional yet great-valued products to release you from the chore of maintenance and taking good care of your beloved pets. From the brand, hygger keeps on providing these products.

The hygger Bio Sponge Filter offers a 2-stage filtration system to help keep your tank water clear and healthy. The fine sponge catches fish waste and tiny debris, while the bio balls provide ample space for a colony of beneficial bacteria to thrive and grow. This combined mechanical and biological filtration efficiently cleans the water.

Moreover, the constant flow of air bubbles rising up from the top and out into the fish tank agitates the water surface, which is great for fish that prefer slow-flowing conditions, such as bettas and fry fish. For better performance, it is recommended to use the filter with a powerhead or water pump to blow up debris for faster cleaning.

Designed with a small and compact size, this sponge filter can be easily hidden behind rocks, driftwood, or other decorations. It is also safe for fish, as the seamless design without any moving parts prevents small fish from getting sucked in. This makes it perfect for betta tanks, shrimp tanks, quarantine tanks, or fry tanks.

The filter's bio balls provide a large surface area for the beneficial bacteria to grow, helping to break down ammonia and nitrate. It requires minimal maintenance, as the sponge only needs to be cleaned with aquarium water every two weeks, and the bio balls require cleaning every two months, with a partial replacement every six months.

Suitable for both freshwater and saltwater aquariums, the hygger Bio Sponge Filter comes in two sizes: Size S (1.8" W x 5.4" H) for 2-5 gallon tanks, and Size L (3" W x 7.3" H) for 6-20 gallon tanks. The filter requires a separate air pump and airline (sold separately) to operate.

For those looking for a tank filter that won't suck in tiny fry and can handle a light debris load, this sponge filter with its gentle water flow is an excellent choice. It is great for fragile invertebrates, such as fry, bettas, guppies, shrimp, and tetras.

Overall, the hygger Bio Sponge Filter provides a simple yet effective solution for keeping your aquarium water clean and healthy, while also gently aerating the water to create an optimal environment for your delicate aquatic creatures.
