My pool cover fell off mid-winter and this is the first time I’ve ever had to deal with a green pool at the start of the season. I’ve slammed before but only once. I had ZERO CYA this morning before starting. I added about 40oz of CYA in a sock in the filter. At last check I was up to about 25ppm. I added 3 gallons liquid shock and my FC is at 26. Should I let the rest of the CYA dissolve, or keep it around 25 for the remainder of the slam? First pic was at 4:30pm, second pic at 8pm.
