AQUANEAT Fountain Pump - Aquarium & Pond

Adjustable flow rate: With a control knob, the maximal flow rate can be up to 80GPH(300L/H); Recommend maximum lift height: 1 foot. 80GPH is the theoretical flow rate at zero lift; the actual output decreases with pipe resistance, lifting height. And the higher the lifting height is, the lower the flow rate will be. For example, the flow rate is 80 GPH at 0 ft (without any water pipe), 40 GPH at 1 ft, 25 GPH at 1.5 ft, and nearly 0 GPH at 2 ft. Measure fountain height before purchase for proper fit.
Optional 2 outlets: Fits 5/16"or 1/2"ID (inside diameter) tubing.
