Chemistry You Need to Know

• Chlorine Stabilizer (cyanuric acid) is needed
to maintain proper levels of chlorine. Most non-
stabilized chlorine is destroyed by the UV radiation
from the sun within two (2) hours. Chlorine
stabilizer should be maintained between 30 - 50
ppm. For indoor pools, it is not necessary to add
chlorine stabilizer to the swimming pool water.
• Nitrates can cause extremely high chlorine demands
and will deplete chlorine from your swimming pool.
In some cases nitrates may even lower your chlorine
levels to zero. Your local pool professional can test
for nitrates. Make sure nitrates are not present in
your pool.
Metals (some metals) can cause loss of chlorine and
•
stain your pool. Have your local pool professional
check for metals and recommend methods of
removal.
• Combined Chlorine (Chloramines) should not
be present in pool water. When organic materials
combine with free chlorine, chloramines are formed.
This ties up the free chlorine in your pool and does
not allow the chlorine in your pool to disinfect.
Chloramines also cloud pool water and burn the
eyes. Shock to remove chloramines at the initial
startup of the pool.
• Shocking or Super Chlorination enhances
chlorine's ability to oxidize organic waste by
eliminating combined chlorine (CC). To measure
combined chlorine (CC), subtract the Free Chlorine
(FC) from the Total Chlorine (TC). (TC - FC = CC).
To determine how much shock (fast dissolving
chlorine) it will take to properly shock your pool,
you'll need to calculate the Breakpoint Chlorine
(BPC) level. To determine the Breakpoint Chlorine
(BPC) needed, multiply the Combined Chlorine
(CC) level by 10. Then, subtract the Free Chlorine
(FC) level.
Here's the Formula:
Breakpoint Chlorine (BPC) = ((CC X10) - FC)
for example: If FC=1.0ppm, and if CC=0.7ppm, the
BPC level would be 6.0 ppm. formula: ((0.7x10) -
1.0)=6.0
Your local pool professional can help with this
calculation or can supply you with test kits that can
provide this information. Running your unit at 100%
for 24 hours may also help you achieve breakpoint
chlorination. If diminished water clarity or evidence
of algae persists, your local pool dealer may suggest
additional steps to sanitize your pool water and
eliminate chloramines.

Chlorine Generating System Installation & Operation Manual ENGLISH
Proper Water Balance is key to your enjoyment of your
pool or spa experience and to the long life of your cell.
• The pH of your pool or spa's water is the measure
of whether water is either acidic or scale forming.
Cold water is typically more acidic, while hot
water is more scale forming. The ideal range for
pH in either a pool or a spa is 7.4 to 7.6 regardless
of temperature. If pH is allowed to rise, above 7.6
and the chlorine generator is operating, calcium in
the water may coat the metal plates in the cell. This
could restrict the fl ow of water resulting in reduced
effi ciency and possibly damage the cell. If the pH
is allowed to drop below 7.4, the water will become
more acidic and will dissolve the metal components
in the pool plumbing with the metal plates in the cell
being a prime target.
Total Dissolved Solids (TDS). Adding salt to pool
•
water will raise the TDS level. While this does not
adversely affect the pool water chemistry or clarity,
the pool water professional testing for TDS must be
made aware salt has been added for the sanitizing
system. The individual performing the TDS test will
then subtract the salinity level to arrive at the correct
TDS level.
New pool water in a recently fi lled or newly
•
refi nished pool may contain undesirable matter
which could interfere with the salt water
chlorinator's ability to sanitize properly. Make
sure the water is tested by a pool professional and
properly balanced before turning on the chlorinator
system. New plaster pools have a constant acid
demand for six (6) months. Test often and maintain a
proper pH to avoid excess scaling of the cell.
Langelier Saturation Index is a standard
•
method of determining the potential of your
pool water to be corrosive or scale forming. PH,
Total Alkalinity (TA), temperature, Calcium
Hardness and Total Dissolved Solids (TDS) play a
role in the calculation of the fi nal saturation rating.
NOTE
On initial startup of a pool, it is best to shock using an
alternate source, i.e., use a shock treatment available
at your local pool supplier.
