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.

4.4 Chemistry You Need to Know

1.
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 2 hours. Chlorine stabilizer should be
maintained between 50 - 75 PPM. See Table 3.
Nitrates can cause extremely high chlorine demands and will deplete chlorine from your swimming
2.
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. Also, metals can stain your pool. Have your local
3.
pool professional check for metals and recommend methods of removal.
Chloramines should not be present in pool water. When organic materials combine with Free
4.
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. (Super
Chlorinate (shock) to remove Chloramines at the initial startup of the pool).
Super Chlorination (Shocking) burns out the organic material that has combined with chlorine.
5.
This frees the chlorine for sanitizing. This is accomplished by raising the chlorine level quickly and
dramatically. When the chlorine level is raised to 5 - 15 PPM the pool water is said to have been Super
Chlorinated (shocked). As pool water is continuously passed through the AquaPure Electrolytic Cell,
all pool water inside the cell is being Super Chlorinated. When the AquaPure is used on pools the pool
water sparkles and does not burn the eyes because of the absence of Chloramines.
NOTE On initial startup of a pool, it is best to Super Chlorinate from an outside source, i.e., use a shock treatment
available at your local pool supplier.
6.
pH produced by the AquaPure is close to Neutral pH. However, other factors usually cause the pH
of the pool water to rise. Therefore, the pH in a pool chlorinated by the AquaPure tends to stabilize
at approximately 7.8. This is within NSPI standards. If the pool pH rises above 7.8 have a pool
professional test to see if other factors such as high Calcium Hardness or Total Alkalinity are the cause
and then balance accordingly.
