So, I've been reading this site for a while and it seems that a lot of posters are battling cloudy or greenish water without much comment on algae on the walls. In our case, our water is nearly perfect - I can see the screw heads at 8 feet down and it looks crystal clear but we have had to slam to clear some green algae buildup at the corners and at the base of the walls. This is starting again. Does this suggest a different problem? Maybe poor circulation? We have a clear solar cover that we leave on for 3-4 days straight most weeks. Pool has one skimmer and three returns plus two in the stairs.
Stenner keeps FC between 6 and 7 with cya of 50 without fail. PH is 7.5 and stable. Cc is never above 0.5. This year, the temp has been steadily around 83f with some help from the heater. We do have lots of trees dropping junk on the pool but my understanding has always been that if the fc was correct, this shouldn't be an issue. I run the robot at least once per week.
