Seachem Reef Strontium

  • Restores and maintains strontium to levels found in natural seawater
  • Strontium gluconate
  • Concentrated (10,000 mg/L)

Strontium occurs in natural seawater at a concentration of about 8 to 10 mg/L. It is chemically very similar to calcium, and many organisms incorporate it in their skeletons along with calcium. Its addition to reef aquariums aids the growth of corals, coralline algae and other organisms that lay down a calcareous skeleton or shell, including triacid clams.

Reef Strontium™ is intended to restore and maintain strontium to levels found in natural seawater without affecting pH. Strontium is utilized in the same manner as calcium and holds a similar importance in maintaining a vigorous level of growth.

Reef Strontium™ contains 10,000 mg/L of available strontium as a gluconate complex. Gluconate complexation confers several benefits: it increases the bioavailability of the strontium, it provides a rich source of metabolic energy to help maintain peak coral growth, and it inhibits strontium precipitation/alkalinity depletion. Gluconate contains no nitrogen or phosphorous, thus it is biologically impossible for it to lead to algae growth in a properly maintained reef system.

Jason E. ★★★★★

My tank's strontium levels were consistently low until I started dosing this concentrated gluconate formula—the 10,000 mg/L concentration makes it easy to restore levels with just a few drops. Corals look noticeably more filled out after a month of use.

Charlotte ★★★★★

My reef tank's strontium levels were creeping down despite water changes, and this concentrate fixed it fast. The 10,000 mg/L strength means a tiny dose goes a long way, and my corals have held their color and growth for over a month now.

Thomas T. ★★★★☆

I've been using this strontium supplement for a few weeks and the gluconate formula seems to dissolve much better than the powders I tried before. My corals have shown noticeably better color, though I wish the bottle listed a clearer dosage for smaller tanks.
