Directions for Use
Assemble the parts making sure that the water exits from the Intake Box through the U-tube and into the Pre-filter Box.
The siphon is started by first filling the aquarium until water flows into Intake Box. Then carefully fill the Pre-filter Box with a cup or two of water. Suck the air out of the U-tube using clear airline tubing (1 ft) until the U-tube is full of water. This is done by bending the airline and inserting it into the U-tube. Be sure the ends of the U-tube are fully submerged so that no air can enter. You may need to add more water to the boxes as you do this. The siphon is now primed and water will automatically reach an even level in both boxes.
NOTE: No air must be allowed to enter the U-tube if the siphon is to be maintained.
If the level of water in the aquarium increases, it will enter the Intake Box and will then siphon into the Pre-filter Box. The water level in the Pre-filter Box will rise until the water flows into the Exit Tube where it will empty into the sump. The main water pump in the sump will then return the water back into the aquarium and continue this cycle. As with any overflow system, it is critical to maintain constant water levels by means of a top-off system or by regular top offs.

Unlike natural aquatic systems, toxic compounds accumulate quickly in an enclosed aquarium system. Without a natural means to efficiently remove these toxic compounds or wastes, conventional aquariums are dependent upon filtration devices.
There are three basic types of aquarium filter media and each performs a different job to help keep a clean and healthy aquarium environment. This article gives a basic overview of the three main types of filter media.
