What do you mean by 'put down', I hope you didn't shoot it . If it is in the primary it should clear up once you rack to the secondary and let sit for a while. If memory serves Corona is a lager, just give it some time and I'm sure it will clear up.
Dont worry about it too much, like everyone says, it will clear once it settles. I brewed a very light colored APA and it was murky to say the least when I sparged. I ran off a lot before sparging, but it was still cloudy. Long story short, I just transfered it to a keg from the secondary, and it flowed nice and clear.
