PP53006 : 530 GPH, Submersible, Aquaponics, Statuary, Hydroponics Pump - 45W, 6' Cord
HOW TO CHOOSE A HYDROPONIC, AQUAPONIC, ALGAPONIC, AQUARIUM, POND OR FOUNTAIN PUMPFirst remember:
Â - "Maximum Flow Rate" is meaningless because it is at ZERO lift.
Â - "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
Â - Continuous instead of intermittent pump duty cycle greatly increases pump life, plus no need for a timer or level control.
<$60) pumps in the 3 to 60 watt pump range are typically submersible.
Â - A rule of thumb is that an average pump will last 2-4 times the stated warranty period.
Â - Best to buy a backup pump if fish or plants depend on the pump.
Step 4: Is A Foam Filter Needed?
A foam filter is not usually needed to protect the pump and the screen cover is enough. If your model has a foam filter and it clogs too fast, best to remove the filter.
Â - If the screen clogs too fast... get a separate pre-filter, vortex filter or settling tank.
Â - Micro-algae will not hurt a pump unless it stops water flow.
Â - Most people buy our filter pumps for the longer 16 foot cord and discard the foam filter.
