IMO the kh will go down naturally over time so I wouldn't do anything.
For the calcium if you can't get it up enough or it just doesn't hold you should check your magnesium level as it is needed to be at proper level to support/hold CA.

You can lower your ALK by using Muriatic Acid. Dosing slowly, as in, dosing in MLS, as this will lower your PH also, but the PH will bounce back. But as CB explained, your ALK will come down on its own in a bit of time, as SW tanks use this up. 12dKH is not a bad number, its the top of wehre it should be, but not over by any means.

I don't want anybody to think that I inferred a dKh of 12 is too high. I was simply saying that the higher the Alk the more stable the pH will be.
Fortunately a nice high Alk is better than a high pH. Or more simply a 12 dKh and 7.6pH is probably better than an 7 dKh and 8.2pH.

No, not entirely, the range basically for ALK is 7-12dKH. So and ALK of 7 and a PH of 8.2 is perfectly ok.
