fishkeeper Aquarium Filter U-V for 10-75 Gallon, 132 GPH Fish Tank Filter for Green Water and Algae Clean, Ultra Silent Submersible Pump Filter with Adjustable Bubble Output for Deodorization Killing

4-in-1 Filtration System – This aquarium filter integrates four key functions: filtration, deodorization, oxygenation, and water circulation. With a flow rate of 132 GPH and a power of 7W, it's ideal for 10-75 gallon fish tanks.

Double filtration for superior cleaning – Features two stages: mechanical sponge filter for debris and activated carbon for odor removal. A 254nm U-V light further reduces green water, ensuring crystal-clear results in a few days.

Independent Control Switches – The fish tank filter easily manage the water pump and U-V light separately. Turn off the U-V light when you only need filtration, providing more flexibility for your tank maintenance routine.

Enhanced oxygenation – Dual water outlets allow adjustable flow, increasing oxygen levels and promoting better water circulation, creating a healthier environment for your fish.

U-V Light Power Failure Memory Function – The U-V light features a power failure memory function that allows you to set its operating time to 3H, 6H, 12H, or 24H, depending on your needs. After a power outage, the U-V light automatically resumes based on the previously set duration, ensuring continuous filtration without the need for manual adjustment.

Deodorize – Designed to combat the unpleasant odors that often accompany algae growth. This powerful aquarium filter helps deodorize the tank, keeping it smelling clean and fresh.

The Necessity of Filter Cotton Cleaning: The filter cotton in the UV filter continuously adsorbs particles such as scale and algae during operation. If the filter cotton is not cleaned regularly, these particles can clog it. As a result, while the filter may appear to be functioning, water may not fully submerge the UV lamp, leading to the lamp operating without adequate water coverage (dry firing).
