Add Cyanuric Acid or Wait?

Last fall pool pump stopped working and instead of spending the money then i waited until a few days ago. I know i should not have done that:confused: Pool is green:( Over the winter i have had to drain out a lot of water due to rain and the cyanuric acid is very low. About 10. As i try to get this green cleared up i am going to have to backwash the sand filter a lot. Is it worth it to add acid before or wait until i have the water clear again?[h=1][/h]

Since it's pretty early in spring it might not hurt too much with less CYA. The risk is that the sun burns off the chlorine faster than iypt can kill algae.
