Our Coral Essentials, Magnesium + Trace is a concentrated source of liquid magnesium, 12,500 ppm (mg/L)  and our own unique blend of Potassium. We have added our Coral Power Potassium into this mix using our proven Coral Essentials Method dosing regiment.


You have two options for dosing:

You can follow our simple recipe and add the following amounts each day:
Soft Coral / LPS System – 3ml per 100L of tank volume per day
Mixed Reef System – 6ml per 100L of tank volume per day
SPS Dominant System – 12ml per 100L of tank volume per day

Or secondly, for optimum results the magnesium levels in marine tanks need to be checked regularly to determine the take up in your system. Simply calculate dosing requirements to suit the depletion rate using our easy to use dosing calculator below. After you have determined this, a regular check of the magnesium levels should be made. Your tank will change over time as coral grows, new pieces are added. We have found ideal magnesium levels to be at about natural sea water levels for most aquariums. Levels of 1300-1350ppm are desirable if you want to maintain high levels of growth in a SPS and hard coral dominant system.
