Hm, that calcium is a bit high. I would try playing with it, buffering the alkalinity and seeing how low you can get the calcium without taking the alk above 4.29.
Is this for a reef tank? Fish only with live rock tank?
I like either Kent's Super dkH buffer or SeaChem's reef builder. This site sells both of them, I believe.

That's all I test for. You may also want to test for phosphates if you have algae problems.

calcium - 400-450 ppm
magnesium - 1200-1250 ppm
so keep my alk and cal within these levels....and this will keep my ph in check correct. I haven't read all of that post you suggested to read, i will though. also where does magnesium fit here. what will this help, i haven't read much about it.
