Hygger Sponge Filter HG120 Large

Filtering and Purifying:

hygger aquarium biochemical sponge filter is powered by an air pump that uses the water-lifting effect generated by rising bubbles and drives water flow through the filter sponge, which can effectively adsorb excreta and residual bait to achieve the purpose of filtering and purifying water quality for saltwater and freshwater aquariums.

Key Features of the Bubbler:

① Oxygenation: An integrated plastic airstone delivers ample bubbles and a gentle water flow to provide oxygenation.
② Filtration: The dense biochemical cotton in the upper layer effectively absorbs impurities, pet waste, and debris. The circular concave design expands the filtration area, enhancing filtration efficiency.
③ Cultivation: The bottom chamber features bio-ceramic media, which promotes the growth of beneficial bacteria essential for aquarium health.

Ideal for Small to Medium-Sized Aquariums:

This air-driven biochemical filter, measuring 2.9 inches in width and 3.7/5.5 inches in height, is ideally suited for 1 to 20-gallon tanks with a depth of less than 12″/15″. It is also ideal for low-flow applications, such as breeding and housing bettas, snails, shrimp, and more.

Maintenance and Filter Replacement:

All the aquarium biochemical filter parts are designed to be easily detachable, facilitating assembly and disassembly. The filter comes with two reusable sponges. It is recommended to clean the filter assembly with tank water every 2 to 4 weeks or whenever bubble production noticeably reduces. This routine cleaning ensures the filter’s ongoing efficiency.
