I've just done the spring pool opening process, and actually it was in good shape this year (no green water or green stuff round the edges this year!).
Previously (having first netted out any larger debris and vacuumed smaller settled debris to waste) I've added shock chlorine to the water and scrubbed off any algae etc, then vacuumed the settled dead stuff to waste, then have always added floc to get the cloudiness out of the water and settled on the floor then I vacuum that out to waste.
This year, I've added the shock and brushed as normal, resulting in some settled stuff which I've vacuumed to waste before leaving the filter to run, and the water is now crystal clear! - do I still need to use floc? will there be "invisible" impurities that need taking out of the water with floc? Or can I just leave the floc on the shelf this year?
