Reef Advantage Strontium restores and maintains strontium to levels found in natural sea water. Strontium is utilized by corals in the same manner as calcium and holds a similar importance in maintaining a vigorous level of growth. Reef Advantage Strontium contains 30,000 ppm of ionic strontium. DO NOT OVERDOSE: Excess strontium may enhance the loss of carbonate alkalinity. Do not directly mix with any carbonate supplement. Best if strontium & carbonate additives are added on alternate days or at least 30 minutes apart. Guaranteed Analysis: Strontium (Sr) 3.00% DIRECTIONS: BEGINNER: Use a level teaspoon per 150 L (40 gallons) twice a week. May be added directly to tank. ADVANCED: Check strontium level, then follow dosing regimen above until strontium is adjusted to 8-12 mg/L. Each dose will raise strontium by about 2 mg/L. Size or frequency of dose can be adjusted. Thereafter, use as required to maintain strontium. EXPERT: After determining the strontium depletion rate, set up a continuous drip system. Use the following formula to determine how much to add to your top-off water: t=0.02vs (t=teaspoons to add to top off water, v=volume of tank in gallons, s=amount to raise strontium in mg/L). For example, if you want to raise strontium by 8 mg/L in a 50 gallon tank, then you would add 0.02x50x8=8 teaspoons into the top-off water. HINTS: Use the Reef Status: Strontium to check strontium levels.
