WATER CHEMISTRY TERMS
YOU SHOULD kNOW
8. Total dissolved solids (TDS):
Materials that have been dissolved by the water. i.e. Like what
happens when you put sugar in coffee or tea.
9. Useful life of water (in days):
Water should be drained at least once every 180 days.
Useful life may vary by usage and bather load.
10. Defoamer:
Foaming may be caused by body oils, cosmetics, lotions, surface cleaners, high
pH or algeacides as well as other organic materials. Low levels of calcium or sanitizer can
also cause foaming. Also, double rinse your bathing suits as they will hold residual soap after
being washed.
11. Calcium hardness:
Water that is too hard (over 250 ppm) can promote scale formation in
components and on swim spa surface. Water that is too low (below 180 ppm) may also
shorten the life of metal components on the swim spa.
NOTE:
Always leave swim spa cover open for 15 min. after addnig chemicals to prevent off gas
from damaging your cover, pillows and other critical parts.
