3W Aquarium Filter

great shallow water filter and so quiet and non-disruptive (low flow)

seen bad reviews but it was easy to set up, quiet, low flow, and honestly the best low flow filter for a betta! you’re getting way more than what you would expect for the cheapness of the filter! the cord is a good length and it seems to work well so far.

I bought this for a 1.5 gallon tank. Installed, ran it for a week, added conditioner to the water and everything appeared to be working great. The water was clean, the pump was running quietly and had a pretty good suction for its size. Then I added 5 small blue velvet shrimp to the tank. Very small, couldnt even see their waste yet and they had live plants to feed on. Its been 6 days now and 4 of the 5 shrimp have died, the water is murky with a green tinge and there are black and brown bacterial or fungal blooms popping up here and there. The first shrimp died after 3 days, it took no time at all for the tank to begin to gunk up. I have never seen his before, but upon removing the pump it is filled with sludge and god knows what else. I should also note that the filters themselves dont seat very well inside the pump, its practically free-floating in there. So this thing is going in the trash and I will stick with weekly partial water changes, maybe the last shrimp will survive. DO NOT BUY! Id also like to add that the shrimp are very strong swimmers but its lucky they dont have fins, otherwise Im sure they wouldve gotten stuck inside the vents right away. IF this thing worked it would be terrible for betas with long flowing fins. Take my advice and just flush 9.99 down your toilet to equal the value of the pump + 38.99 for the shrimp in my case. I have kept these shrimp before and they are hardy as hell and not easy to kill. But this water is absolutely disgusting after only 6 days.....

I like my new filter it’s very quiet and work well the only problem was the black hook that came with its broken so I can’t use it .

Used for a week so far. Tanks had murky water and in ONE day they were clear!! Both my aquariums are just under 10 gal. I got some extra filter media which works well in the extra space. Love the white case, looks nice unlike all the black usually offered. I hope this is a long lasting filter pump!! The waterfall is really nice!! Took out my bubbles which always left water spots on lights and tank edge margin. Very happy with the 2 I bought!!

Very easy to use and very quiet and works great for a small tank

I bought this about 2 months ago now. As others have mentioned, the design is flawed and lets both filtered and unfiltered water through. That said, with some slight modifications it’s much better. I simply bought an aquarium sponge and cut it to size to cover the output. As an added my betta swam into it repeatedly, and the sponge stopped him from doing that. Why wouldn’t I just return it instead of buying and modifying a sponge to fit? This sucker is QUIET. I have my tank literally right next to my bed and it’s not a bother at all. I tried several whisper brand filters that were louder (although admittedly if I didn’t have the tank right next to my bed they would have been fine.) Some have mentioned noise. I noticed that when the unit was not filled with water that it was louder. So I can’t say how it would work in a turtle set up or similar. It seems to have actually gotten more quiet over time and is now practically silent in my 10 gallon. In my previous 5 gallon it did an okay job of filtering, but the current was a bit on the strong side. The flow is not adjustable. However in a 10 gallon with the sponge insert the current is low, but circulating, and since adding the sponge the filtration is great. I really wish it wasn’t white, as it does look as others have mentioned, cheap. I have a white tank I’ll be gifting out that I will pair it with, as it will match well. But with my current 10 (which has a black background which I love the look of) it’s really not aesthetically pleasing. All in all this filter is fine for the price, but if you don’t want your fish swimming into it like salmon up a river then it will require modification.

Only had it a few days and it works really well. My daughters 5 gallon tank filter stopped working. I didn't really notice until the water got really discolored, i started a water change and found the filter done for. So i ordered this pump, it came quickly and it has the little tank looking so much better now! Considering ordering a larger one for my 20 gallon tank.

I'm amazed at how quiet this filter is - I've used several different filters and this is by far the quietest, you genuinely can't hear it at all. It creates a nice gentle water flow, which is important in a small aquarium. It is quite chunky though so be prepared for it to take up some space and, as it's white, it does stand out in the tank.

Muy bueno, no hace ruido y es muy resistente

This pump is working well in my one gallon betta tank. It is pretty much silent and water flows easily. I have found that adding charcoal and some foam clears the water better than the little insert provided. All in all, I'm happy with it.

Bought not used but has an American us plug Looks nice just not to well made

It is worth for the money.The quality is good,and noise level is almost nil.
