Why would you prefer some esoteric answer over the far more likely and straightforward solution?Is there something else to test for that is not usually tested that could be giving me this issue. Its not phosphates, nor algae. What else could impede my fc?
I'm done posting. I don't need criticized. Thank you for all that genuinely wanted to help. I was going to update so that anyone in the future that had to contend with my personal conversion to saltwater would have an easier go at it. The tech at circupool agreed that this is not an algae issue. He gave me three specific things to do.

2) This one stuck out at me and no one caught it (or I missed it). What algaecide are you using? some of them react with chlorine and so you may be creating a chemical soup that sucks all the Chlorine out of the water and you are not realizing it.Observations:
1) I can not keep fc in (or any chlorine in).
2) I have been using algaecide
3) The pool has been sparkling clear, even in the 10' deep section
4) Phosphates at 50 ppb
4) I NEVER used so much chlorine in a season EVER, including years when the pool was brown, including a following year we didn't even open the pool. There were years I never had to put in ANY shock whatso ever, as eventually the chlorine would build up just from the 2 offline chlorinators.
5) I appreciate all the conventional methods, advice, etc. There is no algae, do not know why the chlorine won't come up.
