Added a pound of shock last night to raise the FC and the CYA
Pool looks pretty darn blue.
Two questions. I have the TF-100 kit.
1) When you do the CYA test are you supposed to wait till you totally cant see the black dot at all ?
2) For the TA test, I know it says to add drops until it becomes RED--but mine just turns a dark pink no matter how many drops I add. Is this correct ?
