First of all, if there is still CYA laying on the pool floor, vacuum it up and let it dissolve in the filter. Secondly, keep your pump running 24/7.

Maintain the chlorine level at 12ppm as consistently as you can as I outlined in post #6 above. Test as many times per day as is possible --- no such thing as too often --- and each time, add enough bleach to get back up to 12. When you can go from sundown one day til sunup the next without losing more than 1ppm of chlorine, then you can let the cl drift down and keep it between 3-6 all the time.

Add about 3.5 lbs. of CYA to a sock and hang it in front of a return jet or slowly add it to the skimmer so that it won't clog the pipes. Then run the pump 24/7 for at least the next 4 or 5 days to get it all dissolved.

Your pH is a little high. You can use a little muriatic acid to lower it a little. Add about a pint slowly in front of a return jet. Wear gloves, glasses, stay upwind of fumes and pour close to the water surface to avoid any splashing. After a couple of hours, retest pH and add more if needed until the pH is somewhere between 7.2-7.8. Do NOT test pH when the chlorine is high or you will get a falsely high pH reading. Test it before adding chlorine.
