Hello everyone.
Been a pretty good year so far after the pool rebuild. Pool has been great all year and the robotic pool cleaner has let me sit back and relax. I have a question I have noticed after a good rain that my free chlorine tends to rise a bit. For example before the rain it was testing around 6.5 after a day of off and on showers it tested at 8.0 the pool has salt chlorination and has been very consistent throughout the summer. I have dropped from 35% to 25% in the last two or three weeks. All my test are spot on except ch which has always been at 60 and I have seen a decline in cya from 70 to 60 and was thinking that the reduction in cya may be causing the higher free chlorine tests. Just a theory any one seen any thing like it?
