My CYA is on the high side around 100-120. With winter just around the corner, was thinking of letting the pool stay green from november through april next year. I remember reading threads about decreased CYA over the winter months, and how algae may actually consume it over this period of time? Is that a viable option, or was it just guesswork on the posts? I'm in FL so the winters aren't harsh, so i'm sure algae will have no problem staying around.
