The scheme I proposed requires a sealed (air-tight) container located above the tree stand. The hose delivers water when the water level in the tree stand drops below the end of the hose, allowing air to enter the hose, releasing water. When the hose end is in the water in the tree stand no air gets in, and no water flows. Maybe his system is easier to make aesthetic. -Denis
