HOW TO CHOOSE A HYDROPONIC, AQUAPONIC, ALGAPONIC, AQUARIUM, POND OR FOUNTAIN PUMP First remember:  - "Maximum Flow Rate" is meaningless because it is at ZERO lift.  - "Maximum Head/Lift" is meaningless because the flow at that height is only a trickle. You need to choose an affordable quality pump that produces the "desired flow at your required lift" at the lowest wattage. Step 1: Determining Desired Flow Rate Hydroponic Systems - typically flow through a single loop allowing a single pump and need a flow rate near 100 GPH for each grow bed loop up to 120 feet. Flood/drain beds - need 2 to 4 cycles per hour. Fish tanks - need a least one exchange per hour or extra oxygenation. Waterfalls - need 100 GPH for each inch of width. Step 2: Calculating System Lift Measure the "vertical distance" from the "top" of the water in the pump tank to the pump discharge point. Step 3: Pump Selection Considerations  - Continuous instead of intermittent pump duty cycle greatly increases pump life, plus no need for a timer or level control.
 - A rule of thumb is that an average pump will last 2-4 times the stated warranty period.  - Best to buy a backup pump if fish or plants depend on the pump. Note: A foam filter is rarely needed, a screen cover is enough. DO NOT USE WITH SOLAR POWER! Voltage often fluctuates below requirements.
