I just had a big party. I too use bromine. I added 4 tbl spoons of shock to my tub and ran the boost cycle. Company came later in the day, used tub most of the night and when they left, I figured about 8 users in total so I added 8 table spoons. I woke up went outside and the water was crystal clear again. Bromine was a little high but the levels came back down quickly, I just left lid off to let sun get at it.
As for you chemicals. If your water is that far out, I would say dump it. If I were you, I would keep my water and figure out just how it works. Get this water good again so the next fill will be perfect.
