General Maintenance
Maintaining Clean and Balanced Water
The water chemistry of a spa must be maintained to assure its cleanliness. Failure to do so
leads to unsanitary water, which is unpleasant and potentially dangerous to both the user(s)
and the spa itself.
Maintaining the spa water’s chemistry includes maintaining its chlorine (or bromine) levels,
its total alkalinity, and its pH. Test the water on a weekly basis to assure that all three levels are
adequate. Using a water softener such as SPAmonthly on a monthly basis is also recommended.
Hawkeye Manufacturing, Inc strongly recommends ONEshock for use with its spas as the
primary means of sanitization. ONEshock is a sanitizer that has been pre-measured for our
spas in dissolvable packets. Throw one packet in the spa for every 250 US gallons of water
(if using the granular ONEshock formula, pour one tablespoon in the spa for every 250 US
gallons). See
Spa Reference Guide
for information on the spa’s water capacity. Most spa
configurations necessitate an application of ONEshock every two to three days.
SPAmonthly is one of the most important chemicals for the spa water. It conditions the
water to reduce irritation to the eyes and skin, reduces the chemical odor, and assists in
stabilizing the water’s alkalinity and pH. To apply, simply open a bottle and pour it in the spa
water once a month.
The spa’s water should not require frequent use of chemical treatments other than
SPAmonthly and ONEshock to maintain adequate levels of alkalinity and pH.
See
Troubleshooting – Common Water Problems
for the appropriate course of action
should the spa water’s alkalinity and/or pH need to be raised or lowered.
