We are preparing to close our saltwater AGP for the first time. I have read the instructions in pool school and various other pool articles. All of them say to bring the pool water to "shock" level. However, none of them explain what the heck "shock level" is. Currently our FC is about double what it normally was during the summer. Here are my latest test readings:
FC: 9
Ph: 7.6
TA: 80
CYA: 45
Am I good to close with these readings?
