Versatile Multi-Stage Filtration for Small Tanks:

Engineered for small tanks, the hygger aquarium internal filter is a powerhouse of multi-stage filtration. Its standout feature is the water-changing function, which simplifies daily cleaning and water change routines, reducing the laborious process. It cycles through mechanical and biological filtration more than 6 times per hour, ensuring a pristine aquatic environment.
The multifunctional accessory head enables various effects, including filtration, oxygenation, circulation, and water change. The flat and narrow design allows the filter to be discreetly placed in a corner of the fish tank.
Beyond filtration, the filter offers 4 types of water outlet effects. The Rain Shower pipe outlet disperses water flow across the water surface, increasing oxygen levels in the tank. The straight outlet provides a powerful circulation with a direct, large flow of water, while the mini-fountain outlet adds an aesthetic water feature to the tank.

Innovative Water Change Feature:

hygger’s innovative water exchange design facilitates quick and easy water changes. By rotating the outlet tap and using the included hose (47.2 inches), you can change part of the tank water without completely emptying it, aligning with scientific fish husbandry practices and allowing fish to adapt to the gradual change.

Landscaping and Oxygenation:

To create a fountain effect and increase dissolved oxygen:
1. Pull out the outlet tap.
2. Remove the small accessories.
3. Attach the fountain accessory head to the water change tube. Once powered, the internal filter operates similarly to a small fountain, enhancing the tank’s aesthetic and oxygen levels.

Stability, Durability, and Versatility:

Equipped with a robust 4-suction cup system, the hygger internal filter ensures a stable and secure placement in your aquarium, resistant to loosening. The strong motor runner is designed for durability, ensuring long-lasting performance. Water enters the filter through upper and lower holes on one side, preventing entrapment or attraction of fish.

Enhanced Internal Filter Materials:

Building upon the previous version, the hygger filter features compartmentalized filter materials, allowing for organized placement and easy replacement. The materials have been upgraded to enhance filtering efficiency and reduce the frequency of clogging, with the flexibility to swap out for other types of filter media as needed.

Unique Design Upgrades:

This aquarium’s internal filter is the latest design. In addition, the powerful filtering function brings you a clean and clear fish tank.
For use towards the inside of the fish tank: the large flow of water directly outflows, powerfully circulating the water in tanks. Towards the outside of the fish tank: freely rotate the direction of the water outlet. With a 47.2-long hose, the water in the tank can be discharged and used as a water pump.

Ease of Cleaning:

The internal accessories and filter materials are designed for easy disassembly and removal, making cleaning hassle-free.
