Alkalinity Balance, pH up, pH down, Calcium Balance, Water Stabilizer, and clarifier are all swim-safe chemicals. Wait about 20 minutes, and you are free to swim. We suggest adding algaecide, Super Erace, and shock at night, after everyone is out of the pool. It is safe to swim again the next day.
The question says left for 24 hours. I'm not sure what that means, but I hope you didn't turn the pump motor off. When your clearing up your pool you need to keep the filter running 24/7. Yes, you can use a pool floc and the pump turned off, but this should be done after a good shock, filtering, and backwashing. What many people do is add chemicals at the same time. This is where patience is needed. You may have used too much floc. Sometimes it does take 48 hours for the floc to work.
