The Filter, on the other hand, has a flow rate of 300 GPH and is suitable for 40-200 gallon aquariums. Both the Pump and Filter are required for use with the filter system.

The Filter features a built-in biochemical sponge, which can effectively adsorb dirt and cultivate nitrifying bacteria. It does not need to be replaced, only cleaned regularly. Additionally, the Filter has a built-in 8-inch long clean light, making it easy to check if the light is working. A small hole on the outside of the filter box will indicate a blue light, showing that the internal light is functioning.

The 254nm wavelength UV clean light in the Filter helps to make the water in the fish tank crystal clear by killing green algae. This feature has been professionally tested and proven to be effective. The UV light is built into the Filter, so there is no need for a separate device.

To increase the oxygenation of the water, users can connect an air hose to the Filter. However, it is important to follow the proper steps to ensure the air is being drawn into the Filter and not out of it. First, remove the Filter from the water, then turn the button on the end of the air hose to the loose turntable. Finally, submerge the Filter into the water and turn it on.

The Filter also includes a water outlet with an adjustable angle, allowing users to control the flow of water and create a gentle wave-like motion. This feature can help increase the vitality of the water and make the fish happier.

Overall, the CTUV-H5P Replacement Bulb, CTUV-H8F Pump, and Filter work together to provide a comprehensive filtration system for aquariums. The Filter, in particular, stands out with its double filtration process, separate switches for the pump and UV light, and easy-to-check light indicator. These features help to maintain a clean, fresh-smelling, and healthy fish tank environment.
