4-in-1 Filtration System – This aquarium filter integrates four key functions: filtration, deodorization, oxygenation, and water circulation. With a flow rate of 211 GPH and a power of 9W, it’s ideal for 40-150 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.
Enhanced oxygenation – Dual water outlets allow adjustable flow, increasing oxygen levels and promoting better water circulation, creating a healthier environment for your fish
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!
My tank was so green I wish I had a before pic to show. I couldnât 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 theyâve stayed pretty hungry! I think they wouldâve eaten each other if theyâd been able to see! ð 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.

I have been using this for a while now and I can say itâs been working great for me. Plan to buy a second one.

Died in 5 months
Worked great until the pump died after 5 months, filter sponge rotted in two, and the light was flickering.

Tank cleared in days!
We have a 29 gallon fish tank that we had set up for months and it was clear at first but then got cloudy despite regular water changes, and maintenance. We tried ripping the water changes and changing the filter cartridges sooner and nothing worked. We bought this UV filter and now the water is crystal clear! It REALLY oxygenates the water though so you have lots of little bubbles at all times, but it works well, it’s quiet, and the value is great! It’s a little hard to get apart but it’s very effective and the sponge is pretty easy to clean.
