Brightwell Aquatics Strontion High-Strength Ionic Strontium Supplement for Reef Aquariums Supports Coral Skeletal Growth Aragonite Formation SPS LPS, 2L

Brightwell Aquatics Strontion is a premium ionic strontium supplement formulated to restore and maintain ideal strontium levels in reef aquariums. Strontium is a crucial element in the development of aragonite skeletons in corals, clams, and other invertebrates. Naturally present in seawater at around 8 ppm, strontium supports coral growth and may promote the formation of skeletal material through both biological and chemical processes. Strontion is over 50% stronger than most competing products and contains no unnecessary organics or additives that can impact water chemistry. Maintaining strontium within the 8–12 ppm range ensures optimal conditions for calcifying invertebrates, especially in systems with strong lighting, high growth rates, or dense coral populations. Strontion is made with purified water and pharmaceutical-grade ingredients, ensuring reliable results in SPS-dominant, LPS, mixed reef, and invertebrate-heavy aquariums. Used as part of a complete reef dosing routine, Strontion helps create a stable, vibrant environment for long-term success.
