Coral Essentials, Coral Power Strontium is a concentrated solution of strontium (50,000 ppm). Strontium in natural sea water is in the order of 8-10ppm. Keeping strontium at this level is advisable and not outside the range of 5-15ppm. Anecdotal evidence has shown that strontium at below 5ppm in the marine aquarium is detrimental to coral growth.

Dosage rate: We recommend starting off dosing 1 drop (0.05ml)/day for each 100L of tank water and increase steadily to 2 drops (0.1ml)/day over a period of a month or so. Do not dose higher than 3 drops (0.15ml)/day for each 100L of water for a heavily stocked system.
