How are my numbers?

[reef fool]

Just wondering if you guys would have a prob with these #'s in your reef/fish/invert setup:
Ammonia - 0
Nitrite - 0
Nitrate - 2.5
(kind of a no brainer so far)
Calcium - 420
PH - 8.2
PO4 - .1
KH - 10.4
Alk - 3.7
Was mostly wondering about the Alk/KH
As usual, all advice welcome and appreciated.

IMO 460cal and 5meq alk would be better,but your not far off

I was told....don't smack me if I'm wrong...that calcium much higher than 450ppm would stress out the fish too much.

No smacks are required, this is JMHO, 420Mg is the nominal amount of calcium in seawater with salinity at 35 parts per thousand, so a little more in aquarium water is disirable, mine has been at 510 with no ill effects to fish, but it becomes hard to balance with Alk, just my 2 cents this combo works for me

Your levels seem to be quite good. My levels are almost identical to yours except my calcium is about 410 ppm or so. Although some people might say that they are not optimal or the "best" they are pretty darn good, many people struggle to keep there tanks at those levels. you dont have anything to worry about!!! JMO!
