I'm noticing a handful of green stains at the bottom of my pool. I recently bought the home and switched to a SWG. The plaster is old, stained, and really needs to be remarcited (it's cosmetic so I don't want to spend the money right now). Anyway, I think the green stains may have been there from the start but I'm not sure.
I should mention my FC was super high for a while (11-13) so I really don't think I have an active algae growth. I scrub and scrub and they don't come off. My FC now is 6.5.
Whenever I brush my pool sides and bottom I kick up large clouds of murky water. It gets so bad that I can't see the bottom very well. Note: I'm only brushing and do not have a robot hooked up. Perhaps I should fix the one I have or buy a new one? I can feel debris on the bottom of the pool so I'm not sure how well my bottom drain is working.
