Unfortunately, this isn't going to help to lower your CYA or calcium--when the water evaporates, the CYA and Calcium stay in the pool, just a bit more concentrated until you add fill water to dilute it again. The only way you're going to be able to lower it is if you physically remove it from the pool. However, draining and refilling in small steps is effective, it just takes a little while.

I definitely wouldn't use any more cal-hypo in your pool. Since your CH is so high, I'm sure that it's contributing to your cloudiness problems.
