Pool company closed pool except for closing my electric cover which I'll do. They put in 5 gal of 12.5% Sod Hypo. I already had a FC of close to 20. CYA roughly 120. What level should I be at before I go ahead and close the cover for the winter? I'm estimating FC of around 32 right now.

I know all these numbers are high overall and will resolve on opening in the spring. The cover will also be replaced in the spring. In the meantime what is the highest safe FC level for winter closing? Thoughts? Everything else is balanced.
