So the tank in which I just setup is doing great. a little over 2 weeks and the amoni. and nitrites are gone and nitrates are 12. but the calcium is like 600. I have not added any supplements or any thing. There is live rock but I would not think that It would make the calcium go high. Is there any way that I could make it come down or should I just leave it?

Leave it, test again.. if you have added no calcium to the tank then i would say your kits are bad,WC will not help..
