Hello guys and gals, this is my first post on this site. I am a relatively new service tech, I have a little bit of experience in pool chemistry and chemical basics. When I service a pool I test everything. I have some pools that when I test them on my weekly visit the chlorine levels are in good range, sometimes a little high. I live in San Diego. Lately, I have gotten calls from my customers telling me their pool turned green since my last visit. It kinda is boggling me, as the chlorine levels where good, as were the Ph and Cya levels at my visit.
How do other professionals maintain the chlorine levels when you only visit once a week? Yes they use the pool more in summer, especially the ones with kids, and it has been really hot out here, high 90's on some days.
I am wondering what I can do to not have a pool turn green on me between visits. I just read tablets are a no no, though my customers demand I use them. I realize I am the professional, but when I do not use them and the pool turns green and when they were using them there was no green, kinda think I should continue using them.
Any help would be greatly appreciated. Thanks.
