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.
