Ok so… drain some refill and recheck my levels and go from there?As Marty said above, do not use anymore CAL HYPO as it is just adding to your already high CH.
I would definitely drain to lower the CYA to a more manageable level then use the FC/CYA Levels for proper FC levels. You want to avoid algae even in the cooler months.
You do need to be careful with draining and exposing your plaster to too much sun.
