Chemistry You Need to Know

• Chlorine Stabilizer (cyanuric acid) is needed to maintain proper levels of chlorine. Most unstable chlorine
is destroyed by the UV radiation from the sun within two (2) hours. Chlorine stabilizer should be maintained
between 10 - 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 qualifi ed 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 qualifi ed
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. When experiencing heavy swimming loads or heavy rainfall, use the Boost mode to maximize chlorine
production.
• 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 using an alternate source, i.e., use a shock treatment available
at your local pool supplier.
Never use dry acid to adjust pH in arid geographic areas with excessive evaporation and minimal dilution of pool
water with fresh water. A buildup of by-products can damage the electrolytic cell.
• The pH condition resulting from the operation of the saltwater chlorination system is close to neutral. However,
other factors usually cause the pH of the pool water to rise. Therefore, the pH in a pool chlorinated by a
saltwater system tends to stabilize at approximately 7.6. If the pool pH rises above 7.6 have a qualifi ed service
representative test to see if other factors such as high calcium hardness or total alkalinity are the cause and then
balance accordingly.
• 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. This undesirable
matter could interfere with the saltwater chlorinator's ability to sanitize properly. Make sure the water is tested
by a qualifi ed service representative and properly balanced before turning on the chlorinator system. New plaster
pools have a constant acid demand for six (6) months. Regular testing and correcting of the pH will reduce the
need for manual cleaning of the cell.
• 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 a qualifi ed service
representative about the use of a sequestering agent.
