They will vary depending on the pump size and the turnover rate. The actual number of gallons your filter can manage depends on your pump’s flow rate and the specific needs of your pool (debris load, drains, usage, etc.). You can adjust these capacities if you plan for a different turnover time (e.g., 12-hour turnover).</p> <p><b data-stringify-type="bold">Need help sizing your pool?<span> </span><a href="https://www.vitafilters.com/pages/contact" title="Contact us">Contact us</a><span> </span>anytime - we’re here to help!</b></p> </div> </div> </div>
