My calium and Kh is a bit off.
Ph- 8.2
Carbonate Hardness(Kh)- 20 drops = 358 ppm
Phosphate- .5 ppm
Nitrate- 20
Calcium- 320
What could I use to raise the calcium and lower the Kh?
My corals died except one of them.

Its not like I had many but I just dont want this problem when I put expensive corals in my tank.
Any suggestions on what product I could use? or what I could do?
Thanks!

Double check your test kits against another test kit first.
Mix some saltwater up and test it. If its good, do a 50% water change.
A dKH of 20 is extremely high and the low calcium level would make calcium precipitate out of the water. Is you dont see precipitate, your test kit is inaccurate.

Okay sounds good thanks, and also what do you think caused my xenia coral to die?

I dont know your tank, so it would only be a guess. A broad answer,...
Water too clean
Tank not cycled
Not enough food
Too much water current
Not enough water current
Not enough light
To much light
Xenia eating crabs
Xenia eating predators
To high of a temp
To low of a temp
To high of salinity
To low of a salinity
Xenia stung by another coral
Tank has copper in it
Someone smokes in the same room as the tank or burns candles and incense
Rapid pH drop
Low alkalinity

What is that???!!! Its not bad is it? :(
No, they are not attractive but they are beneficial. Most of them anyway. The one in the picture is definately beneficial. It will eat dead organic matter - leftover fish food, dead snails, etc. The common name is Fireworm or Bristleworm. It's a Polychaete. Poly-Kate is the pronounciation.
