Chemistry You Need to Know

Chlorine Stabilizer for Outdoor Pools (cyanuric
•
acid) is needed to maintain proper levels of
chlorine. Most non stabalized chlorine is destroyed
by the UV radiation from the sun within two (2)
hours. Chlorine stabilizer should be maintained
between 30 - 100 PPM. The addition of chlorine
stabilizer is not necessary for indoor pools.
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
service representative can test for nitrates. Make
sure nitrates are not present in your pool.
• Metals (some metals) can cause loss of chlorine.
Also, metals can stain your pool. Have your
local service representative check for metals and
recommend methods of removal.
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.
Super Chlorination burns out the organic material
•
that has combined with chlorine. This frees the
chlorine for sanitizing. This is accomplished by
raising the chlorine level quickly and dramatically.
• Shocking (Superoxidation) is also a means of
burning out the organic material that has combined
with chlorine. This method involves the manual
addition of chemicals to quickly raise the level of
chlorine. When the chlorine level is quickly raised
to 5 - 15 ppm the pool water is said to have been
shocked.
NOTE On initial startup of a pool, it is best to shock
from an alternate source, i.e., use a shock
treatment available at your local pool supplier.
New pool water in a recently filled or newly
•
refinished pool may contain undesirable matter.
This undesirable matter could interfere with the
chlorine's ability to sanitize properly. Make sure
the water is tested by a service representative and
properly balanced before turning on the chlorinator
system.
• Sequestering Agents may be used in some areas
where the total hardness of your source water
may be unusually high. High total hardness
can contribute to scale formation in the pool.
Sequestering agents will help keep minerals in
solution and under some conditions can prevent this
from happening. Consult your service representative
about the use of a sequestering agent.

Optimum Pool Water Conditions

The following water balance conditions should
be maintained daily to protect the pool finish and
equipment and ensure the pleasing appearance of the
water. The Nature Fusion is warranted to operate
2
properly only if these conditions are met.
Free Chlorine
1.0 - 3.0 ppm. This level may be
lowered to 0.6 ppm with the use
of Nature
exposure to levels above 3.0 ppm
may cause corrosion of pool metals.
Refer to Section 6.2 for Chlorine
Testing.
Combined
None (Super chlorinate to remove
Chlorine all chloramines).
