Bigger pool pumps vs properly sized pumps: Smaller is smarter for most pools

Oversizing your pump wastes money and hurts filtration. A bigger pump costs more, uses more electricity, and pushes water through the filter too fast, reducing efficiency. Calculate your pool’s turnover needs (once every 8-12 hours) and size accordingly — a properly sized pump runs longer but uses less peak power. Variable-speed pumps are even better, letting you run low for filtration and high for cleaning.
