Dozont Aquarium Filter U-V for 20-75 Gallon, 200GPH Fish Filter with 5W U-V Double Light Green Water and Algae Submersible Powerful Clean Pump for Turtle Tank Freshwater Crystal Green Killing

I am thoroughly impressed with the Dozont Aquarium Filter U-V (specifically, the 225 GPH, 55-gallon model)! I've struggled with persistent green water algae in my 55-gallon tank for months, and this filter has genuinely been a miracle worker, clearing the water in just a few days. The overall quality and design of the filter is excellent. It integrates four functions (filtration, deodorization, oxygenation, and water circulation), and the dual filtration system with a sponge and UV light does a remarkable job. The motor runs extremely quietly (less than 50dB) thanks to a pure copper brushless motor, so it doesn't disturb my home life. The filter has a modern, gray look and a compact size (approx. 8.27 x 8.27 x 11.42 inches) that fits nicely in my aquarium stand. It's a submersible unit, so it's hidden within the tank, maintaining a clean and aesthetically pleasing aquarium setup. It feels durable and well-built with a long-lasting UV lamp (rated for 8000 hours) and robust construction that holds up well in the aquatic environment. The water flow is strong at 225 GPH (gallons per hour), ensuring that water is efficiently circulated and treated. I also appreciate that the flow rate is adjustable, so I can customize the current to suit my fish. The odor control is very effective. The UV light and the filter media work together to reduce microorganisms and break down fish waste, which eliminates the unpleasant musty or algae-related smells that used to linger around my tank. I highly recommend this filter for anyone dealing with cloudy or green water issues in their 55-gallon tank. It's a reliable, efficient, and well-made product that truly delivers crystal clear results!

This aquarium filter has made a huge difference in keeping my tank clean and clear. It’s in my 40 gallon tank and works perfectly! It’s very durable my fish don’t care that it’s in there with them. It runs quietly, which is perfect for a peaceful environment, and the water flow is strong enough to keep things circulating without stressing out the fish. Setup was quick and simple, and the maintenance is easy with accessible filter media. My water stays crystal clear, and my fish are definitely happier. A reliable and efficient filter — highly recommend for both beginners and experienced aquarists!

Received the item undamaged. Sponge filter is a large-celled material. Inspected the UV light - no cracks and came on with power. Couldn't see the indicator light at all to let me know the light was working. Washed all pieces in clean water before I put it into my tank. Turned it on - no option to turn the UV light off separately - and the unit immediately began to smell like burned plastic. It stank so badly the tank water began to reek of burning plastic and I could smell it from several feet away. I removed the unit and inspected it - no melting plastic or discoloration or any indication that the unit was malfunctioning. Placed the unit in the tank and let it run overnight. In the morning all of my fish were dead and the entire first floor reeked of burning plastic. Removed the unit - nothing. No signs of malfunctioning or damage to the unit. Returned immediately. Run, run, run away if you value your pets.

This filter is amazing. It has made my turtle tank cleaner than it’s ever been. Highly recommend. These photos are less than a week apart.

The instruction are worst. I had to go off the picture on the box. It is also hard to tell if the light is working. That being said it works great the algae was gone in 3 days and my fish are thriving so the water quality is so much better. It came with a spare bulb which is nice. The filter is a nice touch and is small so I don't worry about shrimp or fry getting sucked up.

It has really improved the performance of my aquarium it was just disgusting with alga but when I cleaned it this time and used the dozing filter I haven’t seen any yet I highly recommend

The filter woks fine but one of the UV bulbs has already burned out after about one month. The Manuel suggests that the bulbs should last about 8,000 hours which is almost one year. How do I get more 5 watt bulbs?

I can’t believe I finally found a product that actually does what it says, I have a 125 gallon aquarium that had a bad bacterial bloom for weeks and for weeks listening to YouTubers on how to clean and they were all wrong this device cleared up my bacterial bloom in 24 hours and the company sent extra bulbs so I’m very excited about this product. Good job dozont

Does a great job. Cleared the algae as indicated. Very happy with the purchase

Good product and value for money.

厳重にプチプチで梱包してありましたが 箱は、潰れていて中身が心配でしたが… いざ電源を入れてチェックした所 殺菌灯が点灯せず 接触の状態が悪いのかと思い 何度か差し替えたりしたのですが 殺菌灯が点灯せずでした 発送前に点検は、しないのでしょうか？ とても不愉快です この商品を購入を考えている方へ 全ての商売ではないと思いますが 私は、お勧めしませんし 二度と購入はしません。
