SLAM

SLAMing is the process of raising your FC high and maintaining it there to kill algae and break down any CC that may have formed. “Shock” is highly misused word, often used for a variety of purposes related to the same goals as SLAMing. SLAMing is something you do to your pool, not a special product that you use. Any unstabilized chlorine is suitable for use in SLAMing.
