HOT TUB WATER BALANCE – GENERAL OVERVIEW
NOTABLE POINTS
•
The reliability and longevity of your hot tub support equipment are directly related to
how well water quality is maintained!
•
The small volume of water in your hot tub is easily affected by the introduction of
oils, lotions, perspiration and chemicals. It is imperative that you give your hot tub
regular attention to maintain clean, safe and balanced water to prevent premature
damage and/or failure (corrosion/calcification) to the support equipment.
Maintaining proper hot tub water balance and sanitizer levels is extremely
important. Neglected hot water will allow bacteria to quickly spread.
•
The mineral content of hot tub water increases due to water evaporation,
sanitizers and other chemicals. If the mineral concentration, particularly calcium,
becomes too high, the minerals will literally “drop” or precipitate out of the water
and deposit on the hot tub walls, plumbing, jets, in the filter and on the heater
element.
•
It is very important that pH be checked frequently and maintained in the recommended
range as indicated in the chart WATER BALANCE SUMMARY FOR YOUR HOT TUB
•
It is also very important that Total Alkalinity (the ability of the water to resist a change in
pH) be maintained in the recommended range as indicated in the chart WATER BALANCE
SUMMARY FOR YOUR HOT TUB
Although there may be two identical hot tub models right next door to each other,
the maintenance requirements will be different, dependant on such factors as:
bather load
frequency of use/quantity of bathers
different body chemistry
sun vs. shade
temperature
For these reasons, it is very important to develop proper hot tub water maintenance habits
and follow your retailer’s recommended water maintenance procedures.
