daily ratio between Alk and Ca

[mrtian97]

Just want to know if there is daily use ratio between Ca and Alk?
Tank is medium stocked with mixed corals (lps and sps), 120 gallon
Thanks

Unless cycling, the tank is likely using close to 1 meq/L (2.8 dKH) of alkalinity for each 18-20 ppm of calcium.

I am adding about that ratio daily through Alk and 2 parts dosing
