Trying to Swim More and do less work

Update:

Around 12pm earlier this afternoon I added a little more bleach to keep my FC up, I added about 1qt just to get a 10(+-) reading during the rain. I checked my PH and it appeared to be creeping up a little Alk was still between 110 - 120.

At 8pm, I did another check and PH creeped a little above 7.2 however FC was right about where I wanted it. (10+-) (Still haven't put any CYA in yet. Since I am planning to begin my metal treatment tomorrow I wanted to keep the PH around 7 so I added 1/2 cup of Muratic Acid. Waited about 45 minutes and took another full reading:

FC = 9.5
CC = 0
TC = 9.5
PH = 7.0 (scaring myself a little because I got the MA measurement right)
ALK = 110-120

Q1. How do I drop the FC? I will need to bring it way down to deal with my metals?

Q2. Do I need to check the CYA even if I haven't added any through Tri-tabs or directly? Does it just get created from a natural process, or from the BBB method?

The FC will come down on its own especially on a hot sunny day. If you haven't added any trichlor tabs or any cya directly, then you do not need to test for it.
