Today the water looked crystal clear, for some reason all of my CYA is gone. Added 6 lbs.

Stains--- Some stains are still there, droped Vitamin C and it desappears. Maybe I should drop more Ascorbic Acid? Maybe not enough Sequestaring Agent? 4 bottles? 35K pool I thought should be enough.

What do you think? I don't want to get cloudy water again.

Thanks,
B
