Just opened my pool and the water is crystal clear. Vacuumed a few leaves, worms out and added 4 gallons of liquid shock. Haven't added anything else. My numbers (using Taylor K-2005 test kit):
Chlorine - 10-20
pH - registering greater than the highest mark (8)
Alkalinity - 170
Calcium - 270 (actually turned purple not blue)
CYA - 50
Should I add anything or wait for chlorine to come down?
