· Bulkhead fittings allow convenient and secure aquarium plumbing
Use these easy-to-install overflow boxes to transport aquarium water to in-cabinet sumps, refugiums, or wet/dry filters. This gravity-feed system eliminates the need for complicated drilling or aquarium modifications. This unit only require 3" of space between the tank and the wall.
Includes: U-tube, round cylinder foam, nylon screw and wing nuts, and pre-filter box, 3/4 bulkhead
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 the Intake Box. Carefully fill the Pre-filter Box with a cup or more of water. Suck the air out of the U-tube using clear airline tubing (approximately 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.
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, which can be added to the sump/filter.

To use siphon box with flexible tubing, purchase the following parts:
