I had to go to the pool store yesterday to get some replacement parts for my ABG pool. While I was there I was speaking with an employee about how nice my pool has been since I have made the switch from Baquacil to chlorine.
Anyway, to make a long story short, he basically told me that I am keeping my FC level too high and that I do not need to use a higher level of FC just because I have CYA in the pool. Basically, he was saying the level of CYA has nothing to do with the FC level I need.
My CYA level is 40ppm and I have been keeping my FC level between 5 and 3 per the CYA / chlorine chart in Pool School.
He is telling me that I should stay between 1.5 and 3 unless I am shocking. He also said that a 16 FC level for shocking is too high.
This guy "seemed" genuine and did not try to sell me anything. He was very supportive of the BBB system I am using.
Now that I have gotten conflicting information in regards to FC level and CYA, I just want my FC level to be right.
I don't want to be "pool stored" and do the wrong thing. Can someone please reassure me?
