Filter Maintenance Your new spa is equipped with an advanced 2-stage water filtration system that provides unsurpassed water quality! To ensure maximum water quality at all times, you should clean and reuse the skimmer bag and both filter cartridges every month. See page 3031 for detailed filter cleaning/replacement instructions. Water Maintenance You will want to replace the spa’s water every 3 to 6 months. The frequency depends on a number of variables including the frequency of use, number of users, attention paid to water quality maintenance, etc. You will know it is time for a change when you cannot control sudsing and/or you can no longer get the normal feel or sparkle to the water, even though the key water balance measurements are all within the proper parameters. See page 35 for additional information.
