The article on Water Balance for SWGs in the Pool School says it is important to have the TA level at 60-80ppm. This recommended range is somewhat lower than the 70-90+ppm shown for pools using bleach and the 80-120ppm range recommended by the SWG manufacturer (Aquarite),the guidelines included in the Taylor testing guide and both pool stores that I use. I am curious about the rationale for this lower recommended range. I did not see one in the Pool Store or the forums. Does the lower range have something to do with the nature of the chlorine generated by the SWG versus other types of chlorine commonly used? What are the relative advantages/disadvantages of maintaining TA in this range versus in the 80-120 range? Are there any disadvantages/negative effects if the TA level is in the 80-120 range? I am all for maintaining the TA in the lower range because I am constantly battling rising pH rising with dry acid, which lowers the TA. Also, when measuring the TA, should I take into account the cyanuric acid correction factor? Thanks.
