I would just stop your additives and let the system use up the excess. What is your PH?

I agree with J...stop dosing for the time being and just test

BTW, 500 isnt HORRIBLE...unlike the guy that went into my LFS and had 900+
^I couldnt imagine how off his other params are

With the lack of stony corals containing a calcium carbonate skeleton(hermatypic) and Tridacna clams as well as other calcareous inverts, calcium isn't needed right now!
As mentioned above halt the dosing of alkalinity booster! Your pH is perfect!!
Having said this however, if everything is doing well in your tank, I wouldn't worry about it too much! A calcium level of 500 isn't detrimental unless your substrate or powerheads etc. are becomming calcified(calcium deposits) due to an excess precipitation(saturation) of calcium that will effect how your equipment performs as well as the amount of oxygen/gas transfer that takes place in the benthic area of your tank!

HI,
I too raised the CA pretty high and the kh and it went down very fast due to a precip event, so better slow down and let that KH come down abit.
I found once it perfect or elevated it stays there for quite a while , I ve cut back to weekly check and don't add anythin till it drop to near 400.
there are limits to calcium so don't pust it..

im just going to let my tank be for a bit. and yes im still going to test but im not going to add the buffer anymore.

Calcium at 500 to me is normal thats where i try to keep mine or even higher up to-wards 600. But my calcium at these levels are not at the expense of the lowered Carbonates and I have not seen where anyone asked you what Magnesium level is running at ? Lower levels of Magnesium usually the cause of this problem. I personally run my Ca. at 500 + and the DKH at 15 or so. My magnesium is at 1500 to 1600.. Have you tested your Magnesium ?
