QuietOne DC pumps range from 132 GPH to 3,168 GPH flow capacity. The small pump is USB powered so it is ideal for emergency use when there is no power so you can run it on a simple USB battery.
4 Modes on the Controller:
Constant Flow Mode: The water flow stays constant but you can control the intensity of the flow from level lowest -1 to strongest level-20. 1 = Min Power Consumption
Constant Flow Mode: The water flows in a wave format with high flow followed by low flow. The high and low intensity wave duration stays the same. You can control the intensity of the wave from level lowest -1 to strongest level-20. 1 = Min Power Consumption
Tide Flow Mode: The water flows in a longer wave format with high flow followed by low flow. The high tide duration is longer than the low tide duration. You can control the intensity of the wave from level lowest -1 to strongest level-20. 1 = Min Power Consumption
