I have read a lot of stuff on the Forum and I have learned a lot so far. Still have a lot to learn .
There is something that shows up very often in discussion in different threads that I don't get at all. It's the proper chlorine level (FC) based on my CYA level. For instead, it is illustrated in "Chemgeek's Best Guess Chart" here http://troublefreepool.com/sticky.php
My questions on the topic are:
1) Why do I have to keep more FC depending on my CYA level?
2) Very often, Forum members say it is a bit different for salt pool using a SWG. I have a SWG and I would like to know why it is different with a SWG?
3) If I try to keep my CYA level between 60 - 80 ppm, what should be my FC with a SWG?
