So... the pool is clear and at 4:30 the readings were:
Cl 10-12 let's say 11 using 3:1 and 4:1 after a full day of sun,

pH 6.8 (a whole box,ok?
TA 50 (9lbs baking soda? and see what I get tomorrow?)
CYA 30 (just glad I can measure it!, should I adjust?)

The only thing greater than your patience has been your advice (or the other way round? Let me know if I'm on the right track...
