Product Information

Strontium works in the same way as calcium to boost healthy skeletal growth. In a well-stocked aquarium, levels of strontium are depleted by corals and other organisms. It's important to replenish these levels to maintain the health of your tank life. Seachem Reef Strontium will restore these levels to those naturally found in sea water (around 8 - 10mg/L) It will also benefit the development of clams and other organisms that have a calcareous skeleton or shell. This product contains high levels of strontium as a gluconate complex. This means it increases the absorption in the water to enable corals to consume it easily. It doesn't contain any nitrogen or phosphates, so will not cause algae growth.

Key Features:

  • Calcium to boost healthy skeletal growth
  • Restore these levels to those naturally found in sea water
  • Benefit the development of clams and other organisms
  • Will not cause algae to grow


Use 1 capful (5 ml) per 80 L twice a week. Check strontium level, then follow dosing regimen above until strontium is adjusted to 8-12 mg/L. Each dose will raise strontium by about 0.6 mg/L
