Modern Reef Strontium 1L

What It Is

Modern Reef Sr+ Strontium is a highly pure strontium supplement designed to maintain and correct strontium levels in marine reef aquariums. Strontium is a naturally occurring element in seawater that is incorporated into the skeletons of many calcifying organisms, including corals and coralline algae.

Why We Like It

Strontium is one of the many elements consumed as a reef aquarium matures, particularly in systems with significant coral growth and strong calcium demand. While it is not required in the same quantities as calcium, magnesium or alkalinity, maintaining a balanced level helps replicate the natural chemistry of seawater.

We like the Modern Reef approach because it focuses on correcting individual element deficiencies based on testing rather than routine dosing without evidence. ICP analysis can help identify when strontium has fallen below natural seawater levels, allowing precise supplementation and helping maintain a balanced reef environment.
