Salinity needed for reef tank?

Ranges I recommend for salinity, etc:
35 ppt salinity or 1.026-1.027 specific gravity (35 ppt and 1.0264 is average)
Temperatures from 79-82 degrees (82 is natural average)
 
Anywhere in that range is good as long as you keep it stable.
 
Good info I keep my stats right on line. .23-.25 and 79-82

What about Ca? I tend to shoot for 450.
 
I keep my tank at SG 1.025+/- @ 79F (average). I may bump it up eventually when I go reef. As previously stated, the average SG/salinity of natural seawater is 1.0264/35ppt.
