The Perfect ATO Return

The Perfect ATO Return is by far the most elegant way to plumb tubing over a rimless tank or sump for your auto top off system. Kinks and awkward bent tubes are gone. Tubing can be strategically placed over an edge for a clean look. This is precision made out of ABS plastic and has a 13mm hose fitting to match common aquarium tubing of 1/2" (half inch). Dimensions of The Perfect ATO Return are 27mm x 50mm x 43mm (1 1/16" x 1 7/8" x 1 5/8"). There is one nylon set screw for easy placement on your reef tank or sump. Nylon screws may be white or black, depending on current inventory. Fits on glass or acrylic of a thickness up to 16mm (5/8"). Comes in five colors to match your reef's other plumbing or gadgets. (Does not come with tubing)
