I think you should leave it, natural Ca is about 390ish and the growth of coral is dependent on its ability to expell Ca from its tissue. by increasing the Ca level to 450 you are actualy making it harder for the coral to grow.
my sugestion is to raise the Alk to aproximatly 12dkh while you keep your Ca about 390 to 400. I did this unintentionaly in my new house and I am getting almost twice the growth that I got when I had my Ca at 440 and my Alk at 8-9dkh.
