I slammed the pool a about 3 weeks ago, all was good, but left the pool unattended for 4 days and let my FC drop to .5. Raised it back up to 5 when I got home and been keeping my FC at 4 for a few weeks but I find green algae on the walls every couple of days.
For the past week, I kept my solar cover
Temp 70
FC 4
CYA 35
CC .5
do I need to do another slam?
