My specs came pretty close to what they list on the pail for the H2ocean: 
DkH- they list 8.7-9.8, I've been getting around 9 
Cal- they list 430-460, I've been getting 440ish 
Mag- they list 1300-1380, I've been around 1370 
Pot- they list 380-420, I've been at 410 
 
I keep my salinity at 1.025 and tank at 79-79.5 F, 
hope this helps
