about 3 weeks ago I posted about my pool being very green
Pool looks green, sand filter leaking sand into pool
I SLAMed the pool around 6-28/6-29 for quite a few days and it seemed to pass the overnight test. Everything seemed to be good again. Now I believe algae is growing again. There is a 'layer' around the whole pool. Brushing will clean the area but kick up a cloud of brown, just like the last time algae grew. I believe the lowest my FC went was 2.5ppm about 5 days ago. My CYA was still at 40ppm because I never raised it after SLAMing so I adjusted. The pool isn't quite as green as last time (pics in the link above) but it has looked 'off' for a few days and now has that 'layer' of junk. Should I go ahead and SLAM again? Can I do that at 60ppm CYA?
My results:
FC - 7.5
CC - 0
pH - 7.8
TA - 65
CYA - 60
CH - 50
Before brushing
After Brushing same area
Other side of pool after brushing
