Calcium usage by alk use?

[bubbaque]

@Randy Holmes-Farley I am trying to figure out how much calcium I use per day. I use a calcium reactor, so I can't dose calcium separately to actually see my calcium usage. I am wanting to dose the Red Sea coral colors and you dose by calcium consumption.

My tank consumption of alk is .7 dkh per day. How much calcium does that equate to?

For every 2.8 dkh 18-20 ppm of cal.
So in your case of 0.7 dkh will consume 4.5-5ppm cal.
