Small Aquarium Bio Sponge Filter for Fry, Betta, Shrimp Tank 6-20 Gallon

The hygger Bio Sponge Filter provides mechanical and biological filtration to help keep water clear and your tank healthy. This small sponge filter is fish-safe with a seamless design and no moving parts, protecting small fish from being sucked up. Not only can this aquarium foam filter keep tank water clean, but it also agitates the water by making bubbles, slowly moving the water around, which is great for fish that love slow-flowing environments, such as bettas and fry fish.

Like most sponge filters, it requires at least a 2W air pump and an airline (both sold separately) to run. The convenient plastic chamber allows for quick and easy access to the filter media for maintenance or replacement. The Size S measures 1.8 in W x 5.4 in H and is suggested for 0.5-5 Gallons, while the Size L measures 3 in W x 7.3 in H and is suggested for 6-20 Gallons. This filter can be used in both freshwater and saltwater aquariums.

The fine sponge material catches fish waste and tiny debris, while the bio balls provide plenty of space for a colony of beneficial bacteria to thrive. This two-stage filtration system helps to keep the water clear and your tank healthy. The seamless design without any moving parts ensures that small fish are protected from being sucked up, making it perfect for shrimp tanks, quarantine tanks, or fry tanks.

The air pump-driven filter provides aeration to the water, which is essential for the health and well-being of your aquatic inhabitants. The slow movement of the water created by the filter is ideal for fish that prefer a slow-flowing environment, such as bettas and fry fish. This filter can be used in both freshwater and saltwater aquariums, making it a versatile and reliable choice for a variety of aquarium setups.

The convenient plastic chamber allows for easy access to the filter media, making it simple to maintain and replace as needed. This ensures that the filter continues to provide effective mechanical and biological filtration for your aquarium, keeping the water clean and your fish healthy. Overall, the hygger Bio Sponge Filter is a reliable and efficient filtration system that can help you create a thriving and well-balanced aquatic environment.
