One of FREESEA's featured products is the 8W Adjustable Sponge 2 Stages Filtration System, designed for 40-120 gallon fish tanks. This aquarium filter, equipped with built-in filter sponges and biochemical materials, offers high operating efficiency and low power consumption, making it perfect for large aquariums. The filter's 2-stage filtration system effectively removes impurities, improves the circulation system, and maintains a clean and clear water environment, automatically removing fish waste to create a healthy and sanitary habitat.

The filter's high-quality core shaft ensures ultra-quiet, energy-saving, and highly efficient operation. Its 3-stage filtration system, including efficient biological filtration media, effectively decomposes harmful substances in the water. The filter is secured by 3 strong suction cups, allowing for vertical or horizontal mounting on the glass surface, suitable for various fish tank configurations.

This submersible filter not only maintains water circulation and oxygenation but also generates active bubbles and waves to keep fish entertained. Designed with a high-quality motor, the filter operates in a super-silent manner, making it suitable for use even in the bedroom. The adjustable water outlet angle, with a range of about 120 degrees horizontally and 30 degrees up and down, allows for the efficient dissolution of oxygen in the water, providing more oxygen to the fish and increasing wave patterns.

The filter's scientific structure is easily detachable and cleanable, allowing for effortless filter cartridge replacement without any tools. It also features a flow speed adjustment valve and an oxygen input knob (connected to the air tube), enabling users to customize the water flow and oxygen levels as needed.

This Submersible Water Filter with 3 Filters is an ultra-quiet water filter suitable for aquariums, fish tanks, ponds, and turtle tanks. Users are advised to avoid running the filter in the air and to place it in the water before connecting the power source, as well as to turn off the power when changing the water.
