Perfect for my application
I have this on a 10 gallon stocked with fish from a "sluggish current" invironment. This filter is perfect for this purpose. It filters and polishes the water without creating a disruptive current in the tank; just enough to circulate the water. The indluced foam filter media works great but I recommend purchasing the Biomaxx "S" cartridges to polish the water. I also have one of these on a 2.5 gallon betta tank and 2.5 gallon ghost shrimp/snail tank. It works great on them, as well.Read full review...

Good Product, but required some repair
First, the bad: the flow adjuster had a leak on mine. The leak let air into the water inlet, which would make an intolerably loud crunching sound when it got to the impeller. I fixed this by smothering the flow adjuster in superglue.
It's unfortunate that this was necessary, because otherwise this is a great product. I recommend it to anyone who needs a low-flow, small sized filter without a flow control knob.
I purchased this item to put on the side of a ~14" cylindrical tank, hoping that it would be small enough to fit on the curved edge. It's a perfect fit. My only additional criticism is that, although the inlet can be adjusted, the "shortest" setting is not very short. A filter designed for small aquariums should be adjustable for a shallow depth.Read full review...

Good hang-on-back Filter for Nano Tanks
Perfect for my 2.5 gallon tanks. I have purchased several of these filters and they have not disappointed. I use them with baby fish and crayfish. The Bio Max maintains a water quality necessary for both types of aquatic pets. These are super easy to maintain and only take a quick rinse to put back into service.
Quiet operation and good water output are things I was looking for in a Nano Filter and this one does the job at a great price.Read full review...

Perfect nano/tiny hang on filter smallest size you can find anywhere!
This is the coolest nano (tiny) hang on back filter I have ever seen. It literally fits in my hand. If you are looking for an extremely compact hang on filter, this is it! Exactly what I needed for a 3 gallon round 360 degree I picked up at a thrift store, it needed an upgrade from the horrible under gravel filter included. This size is non existent elsewhere! Comes with 2 different stage (ppm coarseness) sponge filters that are reusable (great for growing beneficial bacteria, no need to buy replacement cartridges, EVER! Has adjustable depth/length intake tube which is nice also. Cycling the nano tank now, can't wait to put either neon tetras or a betta in there!Read full review...

Perfect for nano tanks
I have 3 of these, 2 on 2.5 gallon freshwater tanks and 1 on a 1.5 gallon bowl. Good current adjustment. A little on the loud side but no so loud that it's noticeable over normal room ambiance. Lots of room inside for media. Attractive, unobtrusive design.Read full review...

Small and packed with plenty of power
Very efficient for such a small filter. Has plenty of options to add different media and upgrades. I have one on both a half gallon freshwater and saltwater setups.
