Hello all
My pool numbers look good, and the water is beyond crystaline. But for a week or so, I've been battling with "shadows" on the pool surface that are faint green; I will get pictures tomorrow. Neither a nylon brush nor a careful steel brushing takes them completely out. When I carefully brush them with the steel brush, they seem to fade away a bit, but I don't want to press too hard and I stop.
My CYA is at 30, and I've kept the FC between 9 and 11. Of course, Dorian has thrown rain at us here and there for a few days, but I've monitored the chlorine level daily.
Do I just "surrender" and SLAM? Even though the water is clear? Do I reach SLAM level and keep it there for 2-3 days, still doing oclt?
