I just tested my calcium with an API test kit
My calcium is over 520
My KH 143.2
What can I do to lower the calcium?

API test kits are garbage. Are you dosing calcium? If not, chances are it's a testing error. Regular water changes should slowly bring your calcium parameters in-line with the stated values in the salt mix.
I don’t add any chemicals to the tank, the only thing I run is a media reactor to help control phosphates
What are the dangers of my calcium being too high ?

520 ppm is OK. Some salt mixes start that high. As calcium gets higher, the main concern is just increased chances of calcium carbonate precipitation.

If you want to get an actual value using this kit, add more drops to get to the endpoint. Then add the values together.
