Will this work?

Thanks! My latest results show a calcium level between 625-650. I have read that high calcium can cause cloudy water. I'm just confused as to weather or not this is my current issue, because before I went through the stain removal process the water was pretty clear and I could see the bottom of my entire pool. It became cloudy after backwashing and adding my first small dose of liquid chlorine. I am hoping that I don't need to drain any water, but if I do how much would i need to drain if my fill water has a CH of 100? Thank you.
-EDIT- Nevermind on the water refill amount. I found the Pool calculator, and apparently would need to drain 45% of my pool. That doesn't sound too fun.
