If natural seawater has Alk of 2.6meq/l and Cal of 380mg/l (not sure on this one).

<font size="2" face="Verdana, Helvetica, sans-serif">Full strength seawater at 35ppt salinity has 410-450 m/l calcium, and Alk of 2.9 roughly.

I have never gone below 420Ca/Alk about 3.1 (with DI, now RO/DI), but there are many other variables to consider as well, the most important of which I would consider to be occupants, water change size/frequency and salt mix.

Just MHFO of course. [img]smile.gif[/img]
