When you first open your pool for the season, run the filter for at least 24 hours. This continuous operation helps to circulate the chemicals thoroughly, clearing out any bacteria or algae that may have developed during the off-season. Subsequent to this initial period, adjusting the run time according to pool usage and water clarity is essential. Keeping the water moving helps prevent algae growth and ensures your pool remains clean and safe for swimming.
