“Now I get it....when we take the cover off in March.....SLAM THE POOL and it'll be good for the rest of the year.”

Or close your pool when the water temp is below 60, bring your FC up to slam level a couple of days before closing. Open your pool before the water temp goes above 60, adjust chemicals after testing, use liquid chlorine until the water is warm enough for the SWG to kick in. You will open to a blue pool and shouldn’t need to SLAM, just need to vacuum and skim.

My pool looked great when I opened it this year.
