To add to Watermom:
Welcome!

Since you have a concrete pool, you'll need to consider lowering Total Alk, expecially since your Calcium is close to 400.

Follow the steps in the Alkalinity forum to lower Tot Alk--remember it's a ratcheting-down process--the aeration is to raise pH w/o raising Tot Alk.

Since your FC is 11, that should be an OK level to keep FC at with such a high CYA--you want to keep it between 8 and 15ppm for CYA levels between 100 and 200.
