Chemistry You Need to Know (Continued)
2.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. The local pool professional can test for Nitrates. Make sure Nitrates are not present in your pool.
3.Metals (some metals) can cause loss of chlorine. Also, metals can stain your pool. Have the local pool professional check for metals and recommend methods of removal.
4.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. (Super Chlorinate (shock) to remove Chloramines at the initial startup of the pool).
5.Super Chlorination (Shocking) 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. When the chlorine level is raised to 5 to 15 PPM the pool water is said to have been Super Chlorinated (shocked). As pool water is continuously passed through the electrolytic cell, all pool water inside the cell is being Super Chlorinated. When IntelliChlor is used on pools the pool water sparkles and does not burn the eyes because of the absence of Chloramines.
Note: On initial
6.pH produced by IntelliChlor 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 IntelliChlor tends to stabilize at approximately 7.8. This is within APSP 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.
7.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 IntelliChlor system. The individual performing the TDS test will then subtract the salinity level to arrive at the correct TDS level. See Table 3, page 15.
8.New Pool Water: A recently filled or
Optimum Pool Water Conditions
In accordance with the Association of Pool and Spa Professionals (APSP) standards, it is recommended that the following water balance conditions be maintained on an on going basis to protect the pool finish and equipment and ensure the pleasing appearance of the water. IntelliChlor is warranted to operate properly only if these conditions are met.
Free Chlorine: 2.0 - 3.0 PPM. Above 3.0 PPM may cause corrosion of pool metals
Combined Chlorine (Chloramines): None (Super Chlorinate to remove all Chloramines)
PH: 7.2 - 7.8 (USE MURIATIC ACID to lower pH and Soda Ash to raise pH.)
Chlorine Stabilizer (Cyanuric Acid): | 50 - 75 PPM |
Total Alkalinity: | 80 - 120 PPM |
Calcium Hardness: | 150 - 400 PPM |
Metals (Copper, Iron, Manganese): | None |
Nitrates: | None |
