Good work on the chlorine. Let it drift down on it's own and then keep it in an 8-15 or so range for the rest of the Summer.
Now, you need to get your pH down right away. Get some muriatic acid, use the bleachcalc, and bring it down into a 7.2 - 7.4 range...sooner rather than later. That chalky substance just may be calcium precipitating out and lowering your pH (sooner rather than later) is the solution.
You can't do anything about your high calcium for this Summer so it becomes imperative that you monitor your pH. Keep the muriatic on hand since bleach has a pH around 12 and it's your only logical chlorine source.
In the rainy season, (or when they lift the drought restrictions) you need to drain half of your pool and refill to get your CYA and Calcium at more manageable levels.
Meanwhile, Happy Swimming!
