DJ100, 27 – 92 gph. Completely submersible internal filter can be positioned vertically or horizontally. Although small in size, it delivers mechanical, chemical, and biological filtration. Perfect for aquatic and reptile environment applications. Duetto Multi-Filter is a compact internal filter that efficiently packs maximum features in minimum space.The multi-filter internal chamber has separate components for mechanical, chemical, and biological filtration, permitting easy replacement and cleaning of the chemical and mechanical filter without disturbing the biological filter.The aeration feature mixes filtered air with pumped water to provide complete aeration, improving the oxygen/carbon dioxide exchange. The multiple output adapters allow either flat output for easy direction of water, or round output for easy connection to flexible tubing.The Duetto Multi-Filter is totally submersible and can be positioned vertically against the aquarium wall, or horizontally on the floor of an aquarium or terrarium.Can be adjusted for minimum or maximum flow. fish tank aquarium media filter
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″.
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!)
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.
