I was just on the Pool School page and researching information about how to SLAM. Below is the FC Shock Level chart that I copied from the Chlorine/Cya Chart:
Non -SWG Pools
I'm sorry for being so ignorant but I don't understand what the Shock FC column means. If my CYA is at 40 (for example) but my chlorine is at 1, how much shock to I add to get things balanced?
Thanks in advance for your help!
