Product Description

This is a super quiet power filter that is good for a 10-20 gallon tank. It is easy to conceal inside your aquarium, hide it behind a plant or other decorative object and from the front it is practically invisible.

Other features include: space saving-aquarium can be flush with the wall; clean, clear water from efficient 3-stage filtration. Works in as little as 2" of water, making it ideal for low water level environments like viquariums for turtles, newts or frogs, UL listed.

Insert Bio Bag and foam grid (the front of the grid is marked "front" and should face the front of the filter).

Hang the filter inside the aquarium and press the suction cup against the aquarium glass. Drape wire over the aquarium wall. The lip of the filter should be above the water level, and the bottom of the filter should be at least 1" above the gravel. When positioning plants and other items, leave about a 1/2" clearance around the filter.

Raise or lower the filter by adjusting the filter hanger. Rotate the filter hanger 90 degrees, remove it and replace it in an alternate alignment hole. (In turtle tanks, the bottom of the filter should be submerged in at least 2" of water.)
If the hanger does not fit on the aquarium frame, it can be replaced with an extra suction cup (provided).

Filter is 4 1/4" X 3 1/4" x 9 1/2" high


Filter has a 2 year warranty against defects in material and workmanship.
