I am having trouble thoroughly eliminating all the black spots in my pool. I've been SLAMming for almost 2 weeks.
FC: between 11 and 21
CC: 0
CYA: 45
pH: 7.2
I've brought the FC up to 21 twice so far. At the beginning of the SLAM I had very low CYA so I had FC at 11. After adding 5 lbs, CYA is up to 45. When FC is at 21 I can see some reduction in the number and size of black spots. But I'm wondering how long I need to keep this up because we'd really like to swim again
