SW pool with no CY reading Problem or Not?

[divepool]

I have a SW pool 56000 gal (no typo) My FC 3, PH 7.5, calcium 160, CY 0. salt at 2900ppm, Pool is crystal clear no problems, Question is do I need to add stabilizer to bring CY up? I have not added any Algaecide, Clarifier or anything this year, opened pool and added 6gal of pool shock and 2 1/2 gal of muratic acid to lower PH from 7.8 to 7.5. All I ever add is muratic acid to keep PH in check. Any help would be great.

Is this a commercial pool? There are often regulations that restrict what you can do in commercial pools.

For a residential pool I would raise CYA up to between 70 and 80.

No this is a residential pool. I will go home tonight and figure out the lbs to add to get to 70/80 cya

Thank you
