Have you ever bumped a dosing or top off tube just to find a puddle of water on the floor a day or so later? The Smart ATO universal tube holder can solve that issue by securely mounting your top off or dosing tubing edge of your rimless or rimmed aquarium. Clamps to tanks with rims measuring under 3/4″ thick. With a simple screw adjustment, your top off tubing will be super secure for years to come.
