Optimize your variable speed pump settings. Calculate power consumption and turnover rates at different RPMs to maximize energy efficiency. Fine-tuning your pump speeds allows you to balance proper skimming and filtration with the lowest possible electricity cost.
For standard filtration, most VSD pumps are most efficient at low speeds between 1,000 and 1,500 RPM. This moves enough water for clarity while using very little power.
According to the Pump Affinity Laws, if you cut the speed in half, the power consumption drops to one-eighth. This is why VSD pumps save so much money.
Most saltwater chlorinators and heaters have a minimum flow requirement. You must set your pump speed high enough (usually 1,800+ RPM) to trigger the flow switch.
