Calcium (Ca) along with Alkalinity (Kh) get consumed by corals daily.  This consumption needs to be replaced to avoid corals losing color and growth.  Target range for Ca is 400-450 ppm.  Test often with a quality test kit.  Liquid calcium is typically added with a dosing pump as part of a 2-part dosing system; although manual additions are effective.  Once target levels are attained individually, Ca and Kh (alkalinity) need to be added in equal parts for daily maintenance.  For best results, MECoral Calcium is designed to be used in conjunction with MECoral Alkalinity.

Quick guide: To increase Ca 10 ppm (400-410) in 100 gallons of aquarium water, add 100 ml or 3.4 fl oz.
