Or secondly, for optimum results the calcium 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 instructions below. After you have determined this, a regular check of the calcium levels should be made. Your tank will change over time as coral grows, new pieces are added as well as invertebrates that also take up calcium. We have found ideal calcium levels to be at about 430-470ppm for most aquariums. Levels of 470+ ppm are desirable if you want to maintain high levels of growth in a SPS and hard coral dominant system.Simplified dosage instructions: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.Dosing by Usage:1ml will raise the Calcium level by 1ppm for each 100ml of aquarium volume.Available in 500ml (17 fl. oz.), 2.75L (93 fl.
