PONDFORSE Canister Filter, External Aquarium Filter Ultra-Quiet with Media | Adjustable Flow Rate, Multiple Filtration Approaches, Powerful Water Circulation Cleaning Machine for Fish Tanks and Aquarium

Great filter/pump. It's priming system kind of sucks but once you get it going it's spectacular. I have multiple tanks and typically would buy the Fluval 407. I like this one better with the UV built in. It burns out pretty regularly but when it's working it's phenomenal. Just keep plenty of extra bulbs. So far, So good. Side by side this one is better bang for the buck and the UV works great. It does come with your first extra replacement bulb.

Strong filter capability in a compact size!! Quiet and easy to use and take apart for cleaning. Using filter for a 75 gallon outdoor above ground pond. Pond had so much algae that accumulated on walls and throughout (over the winter- kept pond temperature between 40-43 degrees), could not see through the water; it was like green soup! Two days after installing the filter we noticed clearer water and less green- within five days the water is completely clear down to the bottom- I can see my goldfish again! Most of the algae on the walls have died. It is truly amazing- Ph is a 7!

For the price, this filter performs about as expected. Setup was relatively easy, though the filter media provided was a bit comedically sparse— though media is relatively easy and inexpensive to get, so I don't consider it a ding against the product. The baskets can be stacked and have plastic tabs so they can be pulled out together, which is a minor detail that makes a big difference. The design for the baskets make it so there is only one correct way to reassemble the canister, which is also reassuring since I'm prone to making mistakes in filter reassembly. The tubes and peripherals were much, much easier to set up than my Fluval FX4, which was also handy. This filter needs to be primed manually, but it was simple enough. From there, it was basically plug-and-play. Operation is a bit louder than my FX4, but only marginally so. I have a million spray bars and an HOB filter making it sound like someone is taking an eternal shower in my house, so all things considered it operates very quietly. That all said, I bought this canister filter for a very specific purpose; I wanted a canister that could hold a liter's worth of media, and have the flow toggled down to <50 GPH (the equivalent of a filter made for a 5 gallon tank). A very specific purpose I know, haha. The idea is that I wanted to create an anaerobic environment to grow denitrifying bacteria (water out of my tap has high nitrates, and even plants have a hard time keeping up). For those purposes, this pump is... well, maybe not the best fit, but not unusable. I chose this canister filter over others because I saw that flow could be adjusted— but in practice, it closes both the intake *and* output entry/exit points with the same valve. This is not ideal because when flow is restricted on the intake, the impeller struggles with keeping the siphon working. The end result is a broken siphon that needs to be re-primed. Over and over and over again. Luckily the tubing for the filter is a common size, so one barbed ball valve later and I am now able to throttle the output, and all is well. Or, at least better. With the base hardware, I still would get air leaks from different parts of the system, so I had to get some more hardware to make the system a bit tighter (especially near the intake entry point on the canister, the hose fit onto it with a little too much play). I still hear air occasionally purging out of the spray bar, but I'm not seeing any meaningful leaks. For my purposes I consider it annoying and wish I maybe went with either a media reactor or a more premium filter brand (though the idea of getting a Fluval just to throttle the flow to a trickle seems like a crime). Now I should preface that this part of the review was almost entirely user error on my part (and it doesn't impact my star rating), but I think it's worth mentioning for anyone considering this filter to make sure it suits their needs. The slats on the intake tube appear relatively small, maybe just big enough you could fit the tip of a pencil through. I don't deal much in nanofish, but I do have curious kuhli loaches that are always foraging on my various intakes. You can probably see where this is headed. I noticed my loaches slowly disappearing over the course of a week, and though I had a mounting sense of dread, I was *certain* that they wouldn't fit in that intake. I started looking first in my HOB filter, nothing. Then my FX4 canister— a singular loach was alive and slightly inconvenienced. And then I opened this canister... the smell hit me first. Then 12 of my missing loaches all bobbed up. It was heartbreaking. When removing them, I noticed floppy necks across the board, so I imagine the impeller hit them on the way in. A gruesome way to go, but at least they didn't suffer. By comparison, my FX4's unintended occupant was completely safe as the impeller was housed separately from the intake's path. It would be ridiculous fault a filter's ability to keep unintended occupants alive, so I mostly make mention of this as a consideration for prospective buyers with nanofish (or as a potential failure point if debris gets in the intake and hits the impeller). Initially I tried putting a sponge into the flared base of the intake tube, but that throttled flow to the point of stopping. I then tried a little cut of mesh from an old gazebo canopy's bug screen, which worked perfectly and didn't affect flow at all. All in all, it works about as expected for the price point. If someone were to use this filter as intended on maximum flow, I'd put it at 4 stars. Mostly just knocked down a star due to it being difficult to personalize and modify without additional hardware. An alright filter as long as you don't have the aquatic equivalent of hamsters.

The older pump I had been using (which was never anything special to begin with) developed some issues so I was looking for something cheap that would arrive quickly via Amazon Prime. Let's start with the Pros: - This thing is incredibly quiet. The loudest thing associated with my aquarium is now the air pump. You could potentially have this in a bedroom it's that quiet. - I like that it has a UV light. Will that have any discernible effect? Time will tell. - Seems to do the job. I transferred the biological media from my old pump and my water chemistry is perfect. The water is very clear. - Cheap. Cons: - Cheap. Everything here just feels flimsy and delicate. I'll be pleasantly surprised to get a lot of time out of this pump. I have now learned enough about aquarium-keeping to realize that I'd be best off making the investment into a serious piece of equipment once this goes pear shaped. - The particulate filters aren't just rectangles. When I want to replace them I'll have to do some creative cutting. Not a huge deal but figured I'd mention it. All in all, the pump is doing what I have asked it to do on the terms I wanted. I'm not going to simultaneously credit it for being affordable and fault it for being made of cheap materials. You have to pay for quality. If I were paying for quality and got this I'd be upset.

I am highly impressed with this PONDFORSE canister filter. Assembly and installation were incredibly easy and straightforward out of the box. I currently have it running on my 75-gallon aquarium, and it handles the water volume effortlessly, keeping the tank absolutely crystal clear. One of the best things about this unit is the massive amount of space inside the baskets for different filter mediums. It gives you plenty of room to customize your mechanical, chemical, and biological filtration exactly how you want it. Maintenance is also a breeze, as the canister provides quick and easy access when it’s time to clean or swap out sponges. Best of all, this filter is incredibly quiet. I have it installed inside a wooden aquarium cabinet, and I literally cannot hear it running at all. It offers fantastic value for the money compared to some of the name brands on the market. If you need serious filtration without the background noise, do not hesitate to buy this!

Works great, very quiet . Easy setup and priming was no problem to get everything started. Tubes are plenty long to adjust and place in whatever space situation you need. No leaks cleared up my tank within the first 24 hours. Solid build. Things to keep in mind if it does get noisy there's two things . 1: the propeller needs to be cleaned. Easy to remove clean add some petroleum jelly and re attach . 2: there's something loose in the bottom of the canister. Maybe sand or carbon etc. Just have to remove it from cleaning the inside. Will update after 6 months and into a year for dependability. So far im very impressed.

I have had this canister filter for months now, and it has done an amazing job. I replaced the filters inside with better filters, and filter stones, because what it came with, was not sufficient. This past month, I have noticed that the light burned out, which is fine, I bought a replacement when I originally purchased, but the filter flow has decreased significantly, even after cleaning and replacing all media inside. Side note: Be careful when dumping out the water lol, I had 4 Neo shrimp and two babies that got sucked in….BUT SURVIVED! Lol

Replaced my worn-out Cascade 1000 canister filter. The Cascade was excellent, but the impeller was wearing out causing a rattle and one of the intake valves was cracked causing a small leak. Time for a new one. Price, reviews and features were key in the purchase of this unit. Pros: Easy to set-up and get running. The lift out filter trays is a nice design. With the water shut off on top and being able to remove the intake by itself is a great feature. The Cascade required the whole lid and top to come off for cleaning and maintenance. I use my own filter media, so I won't comment on what was provided. Its whisper quiet and a great value. Cons: Only dislike is the Bell-shaped strainer for the intake. Makes it hard to tell if it's clogged from just looking in the tank. Overall: Good Value, easy set-up, quiet. I plan to buy another for one of my smaller tanks. 75G Cichlid tank

Good design and materials looks fine, but worked for couple of minutes before it stopped then later on the same day worked again then stopped then worked then stopped for good I have tried everything but with no chance to work again, loss of money for me

Très bonne filtration

Funciona de maravilla. Tiene un motor muy potente y recicla el agua muy bien. Se limpia súper fácil. Tiene una llave que corta el agua y las mangueras se quitan del filtro. Lo sacas lo lavas y ya. Maravilloso.

Works good but the bulbs don’t last at all mine burn out really quick

J'avais toujours des problèmes avec ma filtration d'aquarium. Depuis que jai installé ce filtreur externe, je n'ai plus de problème. Je donne 6☆
