The pH will recover on it's own.
Never, ever mess with pH using chemicals. pH can be easily increased by agitating the water or adding a bubbling airstone.
Raising Ca from 360 ppm to 460 ppm was not a problem, though I would not raise it any faster than that in one swoop.
On the other hand, raising Alk from 9 dKH to 11 dKH in one swoop is harmful.
If left alone, the tank should recover and the cloudiness will be gone by tomorrow. Watch the tank carefully and if coral start to show stress, add another 75 ppm of Ca supplement. This is the quickest way to balance Alk and Ca, in fact that is why the water went cloudy. (The extra Alk combined with the Ca to form a precipitate, or in other words tiny particles of Calcium Carbonate. This is Mother Natures way of fixing our mistake.
) If within a few hours of adding more Ca, coral did not start recovering, I'd do a 20-30% water change and or add that bubbling airstone (which raises pH helping Alk and Ca to combine and precipitate and be quickly utilized by coral.)
Alk should not be raised more than 1 dKH in 24 hours and adding the supplement in two portions over 24 hours is the safest method.
