Selecting the right size pump for your pond is essential for maintaining water quality and clarity. A general rule is to choose a pump that can circulate the entire volume of your pond at least once every two hours. For example, a 1,000-gallon pond requires a pump rated for at least 500 gallons per hour (GPH).
However, if you have water features like waterfalls or fountains, you may need a pump with a higher GPH rating to accommodate the additional water movement and lift required. Consider the size of your pond, the type of filtration system you have, and any water features when selecting your pump to ensure it meets the needs of your aquatic ecosystem.
