About 5 days ago I noticed a few baseball sized spots of yellowish stuff on the hill of my pool and a line of it on the crest of the hill. I assume this was mustard algae. At one point last week I had let my FC down to 2 which is below min. I brushed it up and got FC to 13-15 to host a party. After party on Monday:
FC 6
pH 7.4
Alk 90
CYA 50
So I poured 3 bottles of 8.25% bleach in which should've brought FC to 30. (Must alg level). Filter on 24/7, brushed twice left overnight. Tested this morning and I'm at FC 27. Should I add more bleach or let gradually come down to SLAM level of 20 and try OCLT? Thanks for replies.

To be clear, my question was whether or not to bring FC back up to 30 (must algae shock lvl) or let come down to reg shock level. I will OCLT Thurs night.
