 so annoyingJul 28, 2011
By littlemiss
i had this filter for a grand total of a week before installing a new one, i would have taken it back to the store the same day if i had another option for a filter, however i went ahead and purchased the TOM Aquarium Mini Internal Filter 45gph adjustable flow online (which is working perfectly by the way) and waited for delivery. so why is this filter so horrible?
1) the noise is unbearable, this tiny filter for a 3 gallon tank is louder than another filter i have for a 75 gallon tank! unbelievable
2) its made of cheap plastic parts, ( the "lid" broke off during assembly)
the ONLY good thing about this filter is the fact that it is gentle the current is very weak, suitable for my delicate finned male betta.
as for as how it does with actual filtration, for the week i had it, it kept the water clear and well circulated; as far as any long term use i wouldn't know about but honestly in my opinion i wouldn't be surprised if this thing didn't last more than a month, its that flimsy.

 Works great, if you replace the air pumpJul 20, 2011
By Akira Kun
This filter is a clever design using the airlift principle, the rising bubbles force water up the intake tube, flows through the filter cartridge, and returns water back into the tank.
However, like everyone else says the air pump that comes with this filter is pretty junky and not powerful enough. Filters like these need a good air pump, I personally use the AirPod® Air Pump w/Battery Back-Up for up to 55 Gallon Tanks as it's heavy duty enough and lets you adjust the air flow. You can also use a less expensive air pump (or any other reliable one), as long as it's powerful enough it should do the job.
The filter itself is simply built in design but seems sturdy enough (the lid was kind of flimsy) but it does the job keeping the water clean and circulated. If you plan on getting this product, I suggest getting a more reliable air pump and it should work the way it's advertised. I also wish this filter could be sold alone, without the junky air pump included. It would make the price even lower and let people choose which pump they wanted.

It would be perfect if....Jan 08, 2011
By Hannah
I first bought this filter for my 1.5 gallon tank that has a betta fish in it. It was the perfect size for the tank. It did a really good job at keeping the water in the tank clear. At about 8 months after I bought it, the water would only trickle out of the filter. I tried taking it apart, cleaning the filter out, putting it back together (as sometimes gunk builds up in my other filter that slows the amount of workload it can handle). No change. I originally planned to buy a different brand of filter, but I couldn't beat this price and still had some filter cartridges left over. I saw that other people have said that they have bought more than one with better luck. So, I decided to take the risk. I was curious to see what the problem was, so i tried substituting certain parts of the filter with the old one. The problem was definitely the little motor. For some reason it didn't push air through the filter as much as it did in the beginning.
Either way, I do like the filter and I hope this one holds out. Its perfect for a betta fish's tank- and I like the price.

Wrote that review on January 7, 2011 and it is now February 10, 2011 and the filter is no longer working the way it should. The water only trickles out of the filter, making it unable to do its job. I'm sick of having to deal with this.. I would just like my filter to work like it said it would!!! Don't buy this filter unless you want to replace it a month later....(This is the second one I have purchased with the same result.)

 Stopped working in less than a month. LOUD airpumpFeb 08, 2012
By Liz Darcy
This filter is the worst. First problem I had with it is that the airpump's shape is not designed to handle its own vibration. If placed on a wooden surface it will slide until it encounters an object and when it bumps into the object it will make a loud obnoxious noise. So I placed it on some paper towels and it finally stayed in place. Still, this filter was making more noise than the filter I use in my 20 gallon tank.
I put this one in a 2.5 gallon betta tank and after a week I noticed lots of debris floating around in the water which shouldn't be there if you're using a filter. I also noticed that the water flowing out of the filter was down to a trickle. After just ONE week. Apparently the airpump isn't strong enough and loses its ability to function in a week. By the end of week 2 NO water was flowing out of the filter. This filter was a complete waste of money. Seriously, do not buy it.
For anyone who has one of these and finds that it no longer works, here's what you can do with that useless airpump. Use it for a small airstone. That's the only thing it will work for. That's what I did for a while until I got sick of the noise and just ordered a new airpump that is ten times quieter than this thing.

 does its job, but it's loud and requires maintanenceDec 21, 2011
By Maicia
I got this for my 2gal tank and it worked well for a couple of months. the pump was originally a bit louder than i wanted it to be...but then it slowly got quieter until water was just trickling out of the filter. at first i thought it was the pump's motor (as it would explain why it was quieter when less water was being filtered), so i bought another pump...still didn't fix the problem. I took the filter apart and tried to clean all the gunk in the translucent plastic cylinder. You can also pull apart the bottom (where the tubing connects to the plastic cylinder) since it's two plastic cylinders nested together, and clean both of that. I connected my old pump (the one that I thought was broken) and lo and behold, water's coming out like the first day I bought the filter. It'll eventually start trickling out again and I have to clean the gunk out again, but it beats having to go buy a new pump.
