Great little filter
Date: April 22, 2009
"This is a wonderful filter for small tanks. I actually use two of the DJ100s on my 20 gallon goldfish tank ( not really necessary-- one would probably suffice. It just provides excellent filtration for really dirty fish.) I also keep one filtering in a larger tank so that if I need to set up a hospital tank in a hurry, I have a cultured filter to use. Cannot say enough good things about these little filters."

Excellent little filter

"The Duetto 100 was packaged with my River Treasures Collection Aloha Tiki aquarium. It has performed exceptionally well and is very low maintenance."

Good for Fish, Not for Turtles
Date: April 17, 2008
"OK, let's get one thing straight. If you bought this for turtles, take it back now and get something else, like a ZooMed. These filters really aren't designed to manage the volume of waste turtles produce.
.
If you bought it for your aquarium, these little filters are surprisingly effective. Yes, the plastic case can be brittle, so be sure to handle it carefully, especially when renewing the filters. (BTW, sponge filters can be reused if they're not overly clogged, and if you're enterprising, you might be able to disassemble the plastic carbon containers and refill them to save money. I do.) If there's alot of crud in your aquarium, the intakes are small, so they're easily blocked. If the pressure drops, check the impeller assembly for clogs/tangles; be sure it spins freely.
.
Bottom line: It's compact, it's internal, it offers filtration and aeration options (which many in its price range don't) and it's actually pretty inexpensive. Don't overload it (turtles, goldfish) and be sure to maintain it, and it'll do what it's designed to do.

Good
Date: January 19, 2008
"I have three little leopard frogs in a 29 gallon tank. Its a semi-aquatic setup. I use this filter in the water and it works great! Its a bit loud when you use the air intake, which I don't really use because they usually don't need it.
Other then that I really would recommened this item.

good back up
Date: October 27, 2007
"i currently have two of these filters. one of them is used as a back up filter in my 29 gal. tank w/ a pacu, 2 parrots, & 2 tire track eels. it works great catching algae.
my second 1 is used for my firebellied toads. they dont produce a lot of waste so i adjusted it to a lower level. it works good for all i putit up to. i used to also use it for my turtles until i had to get a mega duty filter.

Exellent filter
Date: May 26, 2007
"I bought the duetto 100 approximatley 2 months ago, it has been working very well. I have a 20 gallon tank with 1 koi in it, 2 goldfish and 2 red tailed sharks. I has kept the water clean, and ph stable and the tanks been cleaned only once in this time span. I reccomend this filter to all aspiring aquarists."

"I use the 50 as a secondary filter/ water circulation system for my turtle tank. it doesnt take much to gunk it up, and the impeller is easily broken. Also It cracks easliy during frequent cleanings, and since the media/ intake slots are very narrow, its difficult to remove all the gunk. I can see it working nicer for a small fish tank, but for a turtle tank with even once a week cleanings, it will fall apart."

"Bought this filter because I wanted to put the tank against the wall and the hang-on filter prevented that. Overall I'm satisfied with it and will probably get one for my other tank.
Likes:
Nice, quiet (unless you're using it to aerate), and compact. Comes with extra parts if you want to use it for aeration and a fountain-style outlet. Adjustable angle outlet.
Dislikes:
Needs to be removed from the tank then disassembled to be cleaned. Carbon canister should've been designed with a snap lid to let the consumer use cheaper carbon refills, but it looks like you could break it open yourself. Flow control is inside the unit so if your fish are getting monsooned around you have to unplug and disassemble the unit to adjust the flow. A nice air inlet valve is included, but they should have at least included a short piece of air tubing for when it doesn't reach the surface.

Highly Recommend this filter!
Date: January 6, 2007
"I had my first Duetto for 3 1/2 years and just bought a new one because the water output was getting slow. I never had any problems with it and it keeps my 30 gal. barrel pond immaculate and is easy to clean. It says for up to 20 gal. but I liked it because it's internal. In a barrel, you can't really hook the conventional filters on to the rounded rim. This one has suction cups to hold it in place and they even give you two different options for water effects. I love it and would highly recommend that you try it. It has a two year warranty which more than pays for the unit if you even get just that long out of it. I have two goldfish in mine."

expect them to break
Date: September 16, 2006
"I have gone through 3 of these in my smaller turtle tanks. When they are working, they work great. However, the rod on which the impeller rotates in the motor assembly has broken every single time between 3 and 9 months of continuous use. It's a flawed design, and I cannot recommend it."

Duetto Dudd
Date: June 26, 2006
"I got this filter for my red-eared slider about a year ago,dont get me wrong it filters great, but it dont last. Within 2 weeks I noticed the chemical filtration was blown, within 5 weeks my biological filtration was noticably gone, and after replacing the filter media 150 times the motor has lost a lot of its hold. The filter clears the water up great, but unless you want to spend the money to change the media every 2 weeks I wouldnt buy this filter."

"This filter cleans great, but do not depend on it for long term use. I had bought this filter twice, both times the motor failed. However, it cleans great and polishes the water quickly. This is not the filter for long-term filteration."

"good product, i am on my second one, would probably buy again. Filters need to be cleaned fairly often for max perforance. Performace is very good, filters are alittle pricey but can be rinsed many time before they need to be changed. I should have gotten the bigger size. When in dought, get the bigger one. It works pretty good for what my turtle puts it through!"

Decent filter for decent price
Date: December 3, 2005
"I bought this for my semi-aquatic turtle. I have a 10 gallon tank with about 4.5 gallons of water in the tank. The filter does its job, but I should have bought the larger version because this one seems a little weak. But overall it's not bad because i did get the filter for a decent price on sale here at petco.com."
