 Perfect filter for low water level setups! Nov 02, 2008
By Scott Jorgensen
There are 3 varieties of the Duetto filters. They are:
Mini up to 10 gallon 2-40 GPH 2-1/2" x 1-3/8" x 5-3/4"
DJ-50 10 gallon 13-66 GPH 3-1/4" x 1-1/2" x 5-1/2"
DJ-100 20 gallon 27-92 GPH 3-1/4" x 1-1/2" x 7-1/4"
These filters have all the necessities: a prefilter/mechanical, a biological filter, a carbon/chemical filter and an air intake that allows the air to mix with the water that comes out of the spout. It is also an extremely quiet filter as long as you keep the pour spout below the water line (to prevent the sound of the water splashing). The only slight problem that I can find is that a tiny amount of air leaks around the seal between the filter media container and the top section, but this isn't a big deal since the water level will almost always be lower then this seal. It's also an efficient filter that produces less heat then most others.
You can use the filter as a pump by removing the pour spout and plugging in a hose that has an inner diameter of 1/2".

Best low maintenance filter ever! Aug 25, 2009
By Leticia M. Nogueira

I don't know about fancy aquarium stuff, but I love this filter. You put it in, the tank gets clean and you don't have to clean it as often as the cascade ones! I love it (and the fish do too!)

 Simple and efficient. Nov 03, 2006
By Rod
Ideal for medium to small tanks.
I use it in my fry tanks, with a net covering the water entrance when the baby fish are too small.

An efficient filter + aerator Aug 15, 2011
By Teapot Tales
Really, this device can serve three purposes: it pumps and moves water around (at various power levels), it filters (with 3 stage filtration), and it can mix air with water, so that your aquarium can be properly aerated. In order to take in air, this filter has a sort of a snorkel with a screw-in cap that allows you to regulate the quantity of air being sucked in. The snorkel stays above the water surface, so there is always a reliable supply of air available.
I mean, you get one device that replaces up to three separate contraptions that all would require maintenance, supplies, space, and, of course, electricity.
This filter also requires some maintenance that is easy to perform. Note: never use any harsh chemicals on this device and its filter media. Especially avoid using Windex, because you do not want to kill the biofilter and you do not want any more ammonia in your fish tank!
There are three pieces of filter media in this device: the primary (rough) mechanical filter, the biofilter, and a self-contained basket-like activated carbon filter.
The activated carbon filter piece is a tightly-capped plastic container that needs to be replaced entirely every 4 to 8 weeks. However, there is a way to open the cap on this container. Then you may be able to replace the activated carbon granules with any separately purchased granules or with a mixture of carbon and zeolite. But, if you do not perform this procedure accurately enough, then your might face some cleanup problems or the impeller could get damaged.
The filter is reasonable quiet, unless you run it at the extreme lowest or highest throughput mode. Every setting in between is fairly quiet. It hardly takes up any space inside a tank. Plus, you do not have to modify your tank's cover to accommodate this kind of filter, because it stays completely or mostly submerged with nothing hanging over the edge of your tank.
Note: a brand-new filter may contain some oil inside its pumping assembly, so just rinse it with running water before installing this device for the first time. The manufacturer states that the motor is completely sealed with epoxy, so I guess that you do not have to worry about the motor.
BTW, the fish find this filter to be a great entertainment piece.
Been using for over a year May 27, 2012
By PandaMom
I've been using this in a 20 gal aquarium with tetras, platys, swordtails, etc for over a year and it's been great. I dont hesitate to recommend this filter. It works well and I've never had trouble. I keep it completely submerged so the tank is quiet. You can leave it up above the water a little to create more current, and if you want you can open the little port that lets air mix into the water too. The only reason I dinged it one star is because it cost me about $12-15 every time I have to replace the three different cartridges depending on where I shop to get the parts. I wish it were cheaper for those parts, such as maybe they could sell multi-packs/bulk packs, etc. The carbon cartridges come in a two pack but the sponges dont. So just keep that in mind when you are planning for long term maintenance. This is a very solid filter and overall I love it.
