Start-Up Procedures
1) Test source water for Calcium (Hardness), Total Dissolved Solids (TDS) and metals (i.e. Iron, Copper,
and Manganese). Consult with an authorized Dimension One Spas Dealer if you need assistance testing
your source water. Knowing these three water conditions is important to properly balancing your
Aquatic Fitness System water. Properly balanced water can greatly prolong the longevity of your
Aquatic Fitness System’s equipment and make it easier to maintain healthy clean clear water. The
following three source water conditions typically only need to be tested once, however, you should retest
if you move or your source water changes.
a) Calcium level should be between 200 and 400 ppm (parts per million). If it is not, use Dimension
One Spas -- Liquid Hardness Increaser (Calcium Chloride) to raise the Calcium level accordingly.
If Calcium is above 400 ppm Total Alkalinity may be lowered below 80 ppm to offset the presence of
excess Calcium – refer to: “Langlier Saturation Index”.
(Acceptable Range is 200 – 400 ppm)
b) TDS should be above 300 ppm. Example: If your Calcium is 200 ppm and TDS is only 200 then you
may add Sodium Chloride (common table salt) to raise TDS to the 300 ppm (minimum ppm). 1 oz.
of Sodium Chloride per 100 gallons of water will raise TDS by approx. 63 ppm.
(Acceptable range is 300 – 2000 ppm)
c) If metals are present add recommended dosage of Dimension One Spas -- Sequestrant, while water
is being added to the Aquatic Fitness System.
2) Test Total Alkalinity (TA) and pH using the Dimension One Spas – Spa Test Strips (available in the
Dimension One Spas -- Starter Kits). With the jets turned off, dip the Dimension One Spas – Spa Test
Strips 12-18 inches into the water and swirl three times for an accurate reading (if you are using a
different brand of test strips be sure to follow the procedures as detailed on their container). TA should
read between 80 – 120 ppm, and pH should read between 7.2 – 7.8. Please use the following guidelines
should you need to make adjustments:
a) Water Condition: Total Alkalinity above 120 ppm
Add 4 ounces of Dimension One Spas -- pH/Alkalinity Decreaser (Sodium Bisulfate),with the jets
turned off, into the center of the Aquatic Fitness System. Wait 1 minute, and then turn jets on
high speed for at least 5 minutes. Turn jets off, retest and repeat procedure until the TA reads close
to 80 ppm.
When Total Alkalinity is above 120 ppm the pH will change slower than the Total Alkalinity.

Aquatic Fitness System
2002 Owner’s Manual
13
b) Water Condition: Total Alkalinity below 80 ppm
Add 4 ounces of Dimension One Spas -- pH/Alkalinity Increaser (Sodium Hydrogen Carbonate)
with the jets turned on high speed. Continue running jets on high speed for at least 5 minutes. Turn
jets off, retest and repeat procedure until the TA reads close to 80 ppm.
When Total Alkalinity is below 80 ppm the pH will change faster than the Total Alkalinity.
c) Water Condition: pH above 7.8
First, test and adjust Total Alkalinity per the above instructions then test and balance the pH. Add 1
ounce of Dimension One Spas -- pH/Alkalinity Decreaser with the jets turned to high speed.
Continue running jets on high for at least 5 minutes. Turn jets off, retest and repeat procedure until
the pH reads between 7.2 – 7.8.
d) Water Condition: pH below 7.2
First, test and adjust Total Alkalinity per the above instructions then test and balance the pH. Add 1
ounce of Dimension One Spas -- pH/Alkalinity Increaser with the jets turned to high speed.
Continue running jets on high for at least 5 minutes. Turn jets off, retest and repeat procedure until
the pH reads between 7.2 – 7.8.
Two tablespoons are approximately equal to one ounce and three teaspoons are approximately
equal to one tablespoon.
3) Add Sanitizer.
a) If using Chlorine, add the 2oz. packet of Chlorine included with the Aquatic Fitness System’s
owner’s kit. Run jets on high for at least 5 minutes. Monitor Chlorine level with Dimension One
Spas -- Spa Test Strips (available in Dimension One Spas -- Chlorine Spa Starter Kit) and
maintain a residual of 1 – 3 ppm.
4) After day one, shock the water with 2oz. of Dimension One Spas -- Shock Treatment (Potassium
Monopersulfate) with jets running on high speed. Continue running jets on high speed for at least 5
minutes.
5) After day two, add Dimension One Spas -- Enzyme Formula to reduce water line build-up normally
associated with body oils. Run jets on high speed for at least 5 minutes.

Aquatic Fitness System
2002 Owner’s Manual
14
WATER TESTING:
We recommend testing Aquatic Fitness System water twice a week with Dimension One Spas -- Spa
Test Strips. These are available from an authorized Dimension One Spas Dealer.
Adjust total alkalinity first, when TA is in the proper range, adjust the PH, then check and adjust
the sanitizer level.
TOTAL ALKALINITY:
Total Alkalinity is a measurement of the water’s ability to resist changes in pH. TA (Total Alkalinity) affects
and buffers the pH of the water. With TA above 120 ppm, pH becomes difficult to adjust. With TA below 80
ppm, pH becomes unstable and is more difficult to keep in the ideal range. Proper TA levels also allow other
chemicals to perform optimally.
Follow directions in the Start-Up procedures section for adding Decreaser and Increaser.
pH CONTROL:
All bodies of water have pH (potential Hydrogen), which is a measurement of the Hydrogen ion concentration
in the water. A pH reading of 7.0 is considered neutral, a lower reading is considered “acidic” and a higher
reading is considered “basic”. The proper pH for spa water is between 7.2 – 7.8. High pH (above 7.8) can
reduce sanitizer efficiency, cloud the water, promote scale formation on surfaces and equipment, and interfere
with filter operations. When pH is too high, add Dimension One Spas -- pH/Alkalinity Decreaser. Low
pH (below 7.2) is equally damaging and can cause equipment corrosion, water that is irritating, and rapid
sanitizer dissipation. When pH is too low, add Dimension One Spas -- pH/Alkalinity Increaser.
Follow directions in the Start-Up procedures section for adding Decreaser and Increaser.

Aquatic Fitness System
2002 Owner’s Manual
15
CHLORINE (SODIUM DICHLORO-S-TRIAZINETRIONE):
Chlorine can be used as a water sanitizer for Aquatic Fitness Systems. However, it is pH sensitive. To be
effective, a Aquatic Fitness System’s pH range must be maintained between 7.2 – 7.8. pH levels above 7.8
reduce Chlorine’s efficiency and pH levels below 7.2 causes Chlorine to dissipate rapidly.
The best Chlorine for Aquatic Fitness Systems is granular “Di-Chlor” (Sodium Dichloro-s-triazinetrione),
such as Dimension One Spas – Concentrated Chlorine Granules. It dissolves quickly in moving water and
has a pH of 6. Be sure to add Chlorine while the jets are running and let the jets run on high speed for at
least 5 minutes.
Use Dimension One Spas – Spa Test Strips to maintain a reading of 1 – 3 ppm of Chlorine. If the reading is
below 1 ppm, the level should be raised before the Aquatic Fitness System is used. If the reading is above
3 ppm, it should be allowed to drop to the proper range before use. Read the instructions on the Dimension
One Spas – Concentrated Chlorine Granules container carefully, or consult with an authorized
Dimension One Spas Dealer if having difficulty adjusting the Chlorine level.
Shocking Chlorine sanitized Aquatic Fitness System water at least once a week will help keep
water clean, clear, and odor free by reducing the build-up of “Chloramines”.
Never use Trichloro or Calcium Hypochlorite.
SHOCK TREATMENT (POTASSIUM MONOPERSULFATE):
Even with regular sanitization, “shocking” with non-chlorine Dimension One Spas – Shock Treatment is still
necessary. “Shocking” with non-Chlorine, Dimension One Spas – Shock Treatment is recommended over
“shocking” with Chlorine (also known as “super chlorination”) because it does not add additional sanitizer to
the water. “Shocking” quickly oxidizes contaminants and burns out body waste such as perspiration, hair
spray, lotions, etc. that cannot be removed by the filter. This waste build-up reduces the power of the
sanitizer making the water dull and irritating to the eyes and skin. This waste build-up may also produce an
unpleasant odor. “Shocking” is also effective in reducing Chloramines. Follow the instructions listed on the
label of Chloramines.
Helpful guidelines for shock treatment:
1. If using Aquatic Fitness System 1 – 3 times a week – shock the Aquatic Fitness System with
1oz. per 100 gallons once per week.
2. If using Aquatic Fitness System 4 – 6 times a week – shock the spa with 1oz. per 100 gallons
twice per week.
To maximize the effectiveness of shocking with non-chlorine Dimension One Spas -- Shock
Treatment we recommend shocking at least 24 hours ahead of, or 24 hours after adding any
other chemicals.

Aquatic Fitness System
2002 Owner’s Manual
16
SUPER CHLORINATION:
Super chlorination also quickly oxidizes the contaminants and burns out body waste such as perspiration, hair
spray, lotions, etc. that cannot be removed by the filter. This waste build-up reduces the power of the
sanitizer making the water dull and irritating to the eyes and skin. This waste build-up may also produce an
unpleasant odor. When this occurs, “Free – Chlorine” has become “Chloramine” which is ineffective for
sanitizing. Super chlorinating can eliminate this. Raising the Chlorine level to 10x (ten times) the “Combined
Chlorine/Chloramine” ppm level (existing Total Chlorine minus Free Chlorine) for at least 24 hours will act as
an adequate treatment.
Do not use the Aquatic Fitness System until the Chlorine level of the water has dissipated to
1 – 3 ppm. We also recommend waiting until the water’s Chlorine level has returned to 1 – 3
ppm before adding any other chemicals as this will help maximize their effectiveness.
ENZYME:
Some wastes (such as body oils) may not be filtered and can result in water lines and other aesthetically
undesirable accumulations in the water. Using Dimension One Spas – Enzyme Formula whenever filling the
Aquatic Fitness System, and weekly thereafter, will help reduce these build-ups. This mild enzyme is a
derivative of plants and is an effective alternative to stronger water clarification chemicals. It uses natural
enzymatic processes to “digest” excess waste in the water.
Water lines can be a result of oils present in the water supply. We recommend checking the
filter 24 hours after filling. If the filter is discolored, remove and rinse.
WATER CLARIFIERS:
Use a Polymer based clarifier that is Ozone compatible. Be careful to follow dosage instructions. Using more
than the recommended dose may cause the water to turn milky.
To clear most cloudy water situations, test and adjust for proper TA/pH levels and shock with
approximately 4oz. of Dimension One Spas -- Shock Treatment, and/or 2oz. of Dimension
One Spas -- Concentrated Chlorine Granules.
