Hey Everyone. I've just opened my pool and I have 0 FC so I am doing a SLAM. This is my first SLAM. Since I have 0 FC and I'm guessing at the size of my pool, I added what I thought was the right amount of bleach to get my FC to 10 (my CYA was around 20 so FC at 10 is my shock). I tested my chlorine level after about 10 minutes and I was at 7.5. How long should I wait to test my chlorine level after I put bleach in it? I didn't know if my FC = 7.5 was a false result, if I did not wait long enough.
Your help is greatly appreciated.
