Went out to work on the pool this morning. It's clear but has a green tint to it. I have added well water the last couple of days, but water was greenish before.

Cl 5.5
pH 7.8
Alk 220
CYA lower than 30 but there is some CYA (when tested at 30 the water was cloudy but could still see the dot)

Adding more CYA now. What can I do to get rid of the green tint?
