Pool is vinyl lined AG and the question:
At what PPM of Chlorine will I start to fade the liner ?? I've been keeping it between 10-16PPM
Thanks in advance folks !

I won over the green monster in four days by shocking to 20 ppm, brushing, vacuuming and backwashing. I don't have a vinyl liner and I don't know if 20 is safe for you, but you can check. Seems that your FC level is too low - it shouldn't take so long.
My Taylor kit arrived after I had already "won the war". Before that I guesstimated CYA and pH with strips and store tests. The store read my CYA as 56. Taylor read 60.
Also, make sure your pH is balanced around 7.4 because chlorine won't be as active at a higher pH. I also used polyquat algaecide. If you have a robotic cleaner even better. Needless to say pump should run 24/7 and you should keep backwashing your filter, or the equivalent routine with non-DE filters.
Hope an encouragement from someone who had just "been there, done that" helps.
