Thanks to both of you for responding. I used liquid chlorine, so if I'm correct... this will not help my CYA. I did add 10 gallons of liquid chlorine, so hoping it will take care of my algae issue. I use granular (99% Sodium Dichloro-S-Triazinetrione) which I dilute in water and pour into pool, along with 1" tabs in my floater (98.6% Trichloro-S-Triazinetrione). These are supposedly good for keeping my CYA up, yes? Soooooo... maybe I've been adding too much water with all the vacuuming to waste I've been doing!?

Thanks again for the help. Hoping to share better news very soon.
