PONDFORSE Canister Filter, External Aquarium Filter Ultra-Quiet Water Circulation Cleaning Machine with Media for Fish Tanks and Aquariums

1/3 the price with the same results and purpose of the over priced brands.
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.

A fine filter, but…
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.

Great Filter & Company
Filter performing well and super quiet. The dual function of UV lamp and filter media (added nitra zorb & bio-chem zorb) leaving my 75 gallons tank water crystal clear. Had for a month and no issues. First filter cleaning completed and no leaks. I also coated all gasket and O-rings with Vaseline to ensure no leakage. Last filter I had lasted 22 years. Hoping this one will last 5-10 years as they don’t build things like they use to.Company communications has been excellent. They responded to all my questions within 12-24 hrs. A good product with no company support is overall a bad product.

It very easy to set up and very quiet when it runs

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.

This pump works by siphoning water from the tank then pumping back into tank after going through the filtering process. I found this pump udderly useless it would stop siphoning randomly, I would wake up in the morning and find it not working. I agree with one of the other reviews the tubing is too big and thick they don’t have to be that thick. If the designers went back and used smaller and thinner hoses they would likely find it would work 10 times better. JMOThe pump was returned and I went back to my trusty filter. Personally I say do your research and make your decision. It works for some people and a totally useless for others.
