First one must recognize that both pool maintenance systems expose our loved ones and friends to the highly toxic and carcinogenic compound called chlorine. Visit the CHLORINE AND CANCER section to read recent factual reports and studies.
When one adds the amortized cost of a salt generator (needed for a salt pool) and replacing the cell every few years to the total expense of operating a salt pool the short term cost of these two chlorinated water treatments are not far apart.
Furthermore, chlorine only represents 30 to 35% of the chemicals that are needed to maintain both maintenance systems. Due in part to the increase in algae coming from wells that our water municipalities use to provide water to home owners, chlorinated and salt pools have two or three algae problems during the pool season.
IF a chlorinated or salt pool doesn’t have a couple of algae problems each year we have found there is a high probability that the level of chlorine in a swimming pool far exceeds the 1.0 to 1.5 ppm (parts per million) of chlorine that is recommended.
a) Pool owners using pool service companies – Check the chlorine level of your pool the day after it is serviced, or at least twice a month. This will help to insure that your family’s health is not being jeopardized. In residential pools anything over 2 ppm is poor and over 3 ppm is unacceptable since it represents a major danger to children health.
b) Salt pool owners – In a pool treated with chlorine when the chlorine level is too high or dangerous usually you can detect a strong chlorine odor. However, when chlorine is pumped into water via a salt generator chlorine it odorless. Salt pool owners should check chlorine levels regularly. This is particularly true during overcast periods and rainy days since salt generators automatically run each day and chlorine levels can spike and become dangerously high when it’s not monitored. In addition, since salt is very corrosive a growing number of pool owners are discovering that it can cause damage to stone work and pool equipment that can cost thousands of dollars.
c) Chlorine gassed pool owners – Since this process renders chlorine odorless, responsible pool owners should check the chlorine levels so their family members and friends are not exposed to a dangerous level of chlorine.
NOTE: There are a lot of very responsible pool service companies in the industry and these businesses will always keep the day-to-day chlorine level below 3.0 ppm on residential pools.
Sadly, when pool service companies that are offering chlorine gas treatment, and choose to over-chlorinate a pool, this action is highly irresponsible as it places your health at risk.
