How do I achieve a certain waterfall look?

Choose a waterfall pump to match the height and width of your waterfall. The rule of thumb is for every 1 in. of weir width, you need 100 gallons per hour flow to achieve a “sheet” look.

Divide by two for a “trickle” look.

Multiply by two for a “Niagara” look.

Be sure to check the pump’s specification for the ideal pumping height of your pump at the head of your waterfall. Keep in mind, excessive bend or in-line filters will reduce the flow.
