alk vs salinity?

[146clark]

I'm not worried about rtn or stn at this moment as this system has no corals. As for cal and alk ect those will not be supplied by water changes I will dose with an automated system as all my systems are. The only question is the salinity for an sps dominate ok at 1.023-1.024? Has anyone done this with any luck? Or does everyone just run 1.025-1.026 because that's what the salt manufacturers give there parameter quotes at
