【Specifications】Powerful aquarium internal filter, Power: 8W, Max Water Flow: 165GPH, Size: 7.5*2.9*2.6in, Length of the Spray Bar: 6.2in/16cm, Length of the Power Cable: 4.9FT. Suitable for 10-50gallon fish and turtle tank.
【Excellent filtration performance】 Built-in U-V, not only purifies the water but also makes the green water clear. This fish tank filter pump also has three kinds of filter media: 1 piece of activated carbon cotton, 2 pieces of biochemical cotton and some ceramic balls, which have good filtration effect.
【With Timer】You don’t need to turn the lamp on all the time. With this timer, you can choose to turn on the lamp for 6 hours, 9 hours, 12 hours or 24 hours according to your needs, which can make you more convenient. No matter when and where you are, this timing function will save you trouble.
【Silent Fish Tank Filter】 For this new aquarium filter, we have improved the internal structure of the pump to further improve the sound insulation. Once you put the filter in the water and turn it on, you can barely hear the motor, only the sound of the water spraying out. The noise level is <35dB.
【Unique Design】This fish tank internal filter has two types of outlets: Spray Bar and Duckbill Outlet, and both of which can be rotated 360°. There is an adjustable knob on the spray bar to adjust the water flow of the filter. In addition, this fish filter adds a Minimum Water Level design. And the four sturdy suction cups can securely install the filter in the fish tank without slipping off.
【High Temperature Protection】This fish tank filter has a built-in temperature controller. When it detects that the internal temperature of the water pump is too high, the water pump will automatically stop working, effectively preventing the water pump from being damaged due to rotor blockage.

Customers say

Customers find the aquarium filter to be of good quality, effective at keeping tanks clean and controlling algae, with adjustable water flow and good value for money. The functionality and noise level receive mixed feedback – while some say it works well, others report it stops working after two weeks and is extremely noisy. Customers disagree on the ease of use, with some finding it super easy to use while others say it’s very difficult to take apart and clean. The size also gets mixed reviews, with some finding it too large while others consider it very small.

    Meh, works okay for a very short time
    Edit: within a couple of days of posting my original review, the seller reach out to me and promptly sent me another uv bulb for the filter. The customer service that I received was top notch and they were so adament about fixing my issue. They also advised me that the filter comes with a 1 year warranty in case something was to happen. I would definitely purchase again due to how amazing the seller has been with getting my issue resolved so quick. 110% recommend this product! Give this filter a try bc you will have top notch customer service if something was to end up happening to it within a year after your purchase!Worked great for just over a month but now the light doesn’t work so its basically useless for what I needed it for!

    Really decent at a good price
    Very easy to disassemble and put back together; first thing I checked. Very easy to install. Seems perfect for my pet Green Crab Larry’s 20 gallon saltwater tank. I really like the multiple filter elements combined with the UV and the decent number of ceramic balls for bacteria to set up house. I decided to set it up with the water level mark just below the surface so the long bar (pictured), with the multiple discharges causes bubbles to add oxygen without it being a hurricane tidal wave of water crashing into the tank like some filters. Reasonable price also compared to others at the stores locally with very fast delivery.

    Huge for 5 gallons tank
    Overall, this filter does an amazing job for my 5gallons tank. The tank filter speed is adjustable and able to control the flow. I searched for a long time and finally decided to get this filter. In fact, it works well and much better than I expected. I like the slow water flow because it provides the most comfortable swimming speed for my nano fishes. The non-adjustable filter will make my fishes swimming all the time without a break. Almost like a marathon for them.The size of this filter is quite large. It takes roughly 1/5 of the space in my 5 gallons tank. It is better for 10 gallons or larger tank. The noise level is acceptable. However, 5 gallons tank will be also fine.This filter is hard to open for cleaning and needs a little bit of efforts. I need to open the front frame first and remove the back frame.The 4 stages filtration design is smart. The ceramic balls are good media for building beneficial bacteria.

    good for algae, hard to clean
    UPDATE: although these helped a lot with my blue green algae issue, cleaning them is a pain, the suction cups don’t work well and constantly dislodge, and the rain spout gets clogged with algae and has to be cleaned fairly often. Of the 3 I had, one of the was defective and wouldn’t clasp closed properly from the start. They are decent but wouldn’t but them again, and they do a VERY POOR JOB at actually removing debris. Do the UV feature works, unless you accidentally flip the light upside down (which is very easy to do with regular maintenance) and then you have a light that ENCOURAGES algae growth so…I do love the adjustable nature, but the filter part of the filter is basically useless and a HUGE pain to clean compared to other filters of the same size and type, and I have tried many at this point.I have replaced all 3 and no longer use this model as it does not help clean the tank at allORIGINAL: I love this filter so much I have 3 for all of my tanks. I have two 6g and a 10g for beta fish. I am able to adjust the flow, I was having terrible issue with blue-green algae and this was the game changer in winning the war. I replaced all my filters with the UV-filtering version and am so far exceedingly pleased. I am using the multi-prong output and my tanks are thriving.

    Great product
    Very easy to put together, was a bit bigger than I expected but that just upped the value for the price, there is absolutely no sound you can’t even tell it’s running. I bought it for a three and a half gallon and while it did take up a lot of room I made it work and my green water turned clear. It’s now comfortably in a 10 gallon doing a wonderful job. The only thing it needed was a bit of work in the filter “sponge” area, what came with it was just a course big sponge so I cut it down enough to be able to fit floss in there so it actually catches smaller debris…. other than that it’s perfect and I would buy it again, I would recommend this filter! 👍

    Quiet and adaptable
    Finally thank you!I was looking for ages buying and returning filters with a UV stick in them and you guys made one. Not only is this low flow and medium sized it also has the UV, adjustable flow and is quiet. Perfect filter

    Works well When it does, but not reliable
    I bought this filter back in July and after 4 months its already broken. The first red flag is that it arrived covered in sand, I just washed it off hoping it would be a fluke. It would run fine for a week or so but despite my tank not being large it would clog and bog down super fast, so I was cleaning it a lot. Then the time it took to bog just got faster and faster and now the motor went out. I really wanted a UV filter and I was trying to save some money, but I guess you get what you pay for. I wouldn’t recommend it, also I don’t even think I can return it anymore.

    This filter works perfect while working. Clear the water within 3 days, but very short product life. I ordered it on June 7 and it stopped working last weekend. Only works for 2 months not worth the price.

    Great product, the water in my 20-gallon-long betta sorority tank was crystal clear after a day of running, and after a week I had to remove my algae eaters for lack of food. The flow is too strong for my bettas, so I pointed the water spout towards the glass – problem solved.HOWEVER: one of my beloved bettas got sucked into the slots for the filter intake and died a pretty horrible death 💔 I’ll be keeping the filter (I’ve zap strapped some filter sponge to the intake and covered the whole filter in a stocking) and still give it 5 stars for being effective, but feel I must warn others about the potential dangers of using this filter with smaller fish.

    Filter worked great for a week then the timer quit working and the filter has become sub par. Need to buy another filter prior to returning for refund

    Bought this filter for my ten gallon in February and it worked so well. Recently upgraded to a twenty gallon and for the last week I have had to clean it every day. Now today after cleaning it again, it barely pushes any water out. Just tiny droplets. having to buy a new one a month and a half after buying this one is pretty annoying. Not worth the money.
