Typical filtration cycles are four hours, twice per day (for hot tubs operating a single or two speed pump). Reducing the cycles to 3 hours twice per day will save water pumping energy. These circulation times should be set for off-peak hours. (Some hot tubs have small, low wattage circulating pumps that run 24 hours a day. Typically these draw less energy than a 100 watt light bulb.
Regular Jet Cleaning. To clean the entire whirlpool system and tub exterior, follow this process every month or more frequently if needed. Don't let dirt and grime build up or you'll have more scrubbing to do to get the tub clean. Fill the tub with hot water, approximately an inch above the highest jet. Make sure the water temperature reaches at least 140Âº F (60Âº C). Add 1/2 cup of laundry detergent or the amount used to clean 1 load of laundry as recommended by the detergent manufacturer. Run the jets for 15 minutes.
