Seachem Reef Strontium 250ml – Concentrated Ionic Strontium Supplement

Seachem Reef Strontium is a highly concentrated (10,000 mg/L) gluconate strontium supplement designed to restore and maintain strontium to levels found in natural seawater. Strontium is utilized by corals in a similar manner to calcium and is essential for the formation of aragonite in coral skeletons and the shells of other marine invertebrates. Unlike other strontium supplements, Reef Strontium is formulated to be easily absorbed without significantly impacting the $pH$ of your reef system.

Essential Mineral Support for Coral Calcification

Reef Strontium provides a bio-available source of this critical trace element to ensure robust skeletal development in reef-building corals.

  • High Concentration: A powerful 10,000 mg/L formula, ensuring that even a small dose provides a significant boost to your aquarium's mineral profile.

  • Ionic Bio-Availability: Delivered in a gluconated form that is more easily sequestered and utilized by corals than inorganic strontium salts.

  • Promotes Skeletal Strength: Works alongside calcium and magnesium to create the dense, stable skeletal structures required for healthy SPS and LPS colonies.

  • $pH$ Neutral: Specifically formulated to not disrupt the delicate acid-base balance of your reef, allowing for independent management of alkalinity.

  • Prevents Depletion: Restores levels that are rapidly depleted in high-growth reef systems and through protein skimming and carbon filtration.


FAQ Section: Common Questions

  • How much Seachem Reef Strontium should I add?

    The standard dose is 5 mL (1 capful) per 80 L (20 US gallons) twice a week. For high-demand systems, it is best to monitor levels with a test kit to adjust your dosing schedule accordingly.

  • What is the target strontium level for a reef tank?

    Natural seawater contains approximately 8–10 mg/L of strontium. Most reef hobbyists aim to maintain a range between 8 and 12 mg/L to support optimal calcification.

  • Can I overdose strontium?

    Yes. While strontium is essential, excessive levels can be toxic to some marine life. Always use a reliable test kit when dosing beyond the recommended maintenance levels.
