TA 70 (yay!)
I have a SWG and have always tried to run the CYA at 70. However, this year I did a big SLAM cycle due to tenacious waterline algae and also algae in the pool cleaner hose. Since that SLAM (more than a month ago), my SWG has had NO problems maintaining FC at 5, even with warm water and sunny days. I have had to run it at 100% in the past but I don't have to do so any longer. My CYA was almost 0 before the SLAM, so I SLAMmed the pool and then did 50% of the increase I needed to do and am now at 40. I still have 8 lbs of CYA.
Since the pool is maintaining FC well, should I still increase the CYA? Maybe I can run the FC at a lower level? Maybe the few dots of algae starting to show near the water line are telling me to continue the CYA increase?
