SWIM SPA WATER MAINTENANCE - START-UP
Day Four Skip
Day Five
1. Test and adjust total alkalinity, if necessary, to between 80 and 120 ppm using the pH / alkalinity
increaser or decreaser, 5 oz. at a time. Wait 30 minutes, retest and adjust if necessary. The pump
should be running on high speed during this time with the air controls closed.
2. Test and adjust the pH, if necessary, to within the range of 7.2 to 7.8 using the pH / alkalinity
increaser or decreaser, 2.5 oz. at a time. Wait 30 minutes, retest and adjust if necessary. The pump
should be running on high speed during this time with the air controls closed.
3. Test and adjust sanitizer level. Add chlorine following label directions to maintain a free
chlorine level of 1 to 3 ppm. If using bromine, adjust feeder to maintain a total bromine level
of 3 to 5 ppm. Add bromine tablets to the dispenser if necessary, following label directions.
4. Shock with 10 oz. of non chlorine shock, or superchlorinate following label directions. A swim spa
should be shocked at least once a week even if it is not used. If using chlorine as the sanitizer, the
swim spa should be shocked whenever a free chlorine reading of 1 to 3 ppm cannot be obtained
without raising the total chlorine level above 5 ppm. Always shock a swim spa after any heavy
bather load.
5. Check filter cartridge and clean if necessary. Clean with cartridge filter cleaner, following label
directions. It is best to have a spare cartridge on hand, to prevent long swim spa down times while
the cartridge is being cleaned. Never operate your swim spa without the filters in place.
6. Use a defoamer only if necessary.
Day Six and Seven Skip
With a swim spa you are working with a small volume of hot water compared to a large volume of
relatively cool water in a swimming pool. Because of this chemicals will have a shorted life span and
bacteria can grow more quickly than in a swimming pool. A swim spa is less forgiving than a pool, and
requires that whatever is put into it have a pH as close to neutral as possible. That is why only chemicals
made for swim spas should be used.
