Features

  • 4-in-1 Filtration System This aquarium filter integrates four key functions: filtration, deodorization, oxygenation, and water circulation. With a flow rate of 172 GPH and a power of 8W, the fish tank filter is ideal for 30-100 gallon fish tanks.
  • Triple Filtration for Superior Cleaning Features three stages: mechanical sponge filter for debris, activated carbon for odor removal, and quartz balls for enhanced filtration. 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.
  • 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.

  • Satisfied! Works as advertised!
Size: 12W
My tank was so green I wish I had a before pic to show. I couldn’t see anything in my tank, and changing the water every other day and withholding feedings to every 3rd day for weeks was not touching the green algae bloom. I put this UV filter in and 7 days and 2 partial water changes later, cleared. My fish appear to be grateful bc they’ve stayed pretty hungry! I think they would’ve eaten each other if they’d been able to see! 😂 I personally put a longer piece of tubing on the top so I could run the piece that has to remain above water out a hole on the back of my hood without crimping it. I had it on hand; it uses the regular tubing used on the air pump, FYI. ... show more

  • Good value
Size: 12W
Cleared up the akgea problem in a week. Works very well. Stopped working on second day but it was just a connector inside the control unit. Popped it open, reconnected and working great again. Good value for the money.

  • Last about a month before the pump itself quits
Size: 15W
It was great for a week, but within a month the pump stopped flowing. Impeller spins freely, kept clean and free of debris. Now I'm thinking I'll be returning the second one I bought before the return window closes on that one
