Rubidium (Rb) is a trace element monitored in ICP testing and increasingly recognised as part of stable coral growth conditions in modern SPS, LPS and advanced soft coral systems. While often overlooked, reefkeepers running structured ICP programmes frequently observe ongoing Rubidium depletion, especially in high-demand environments.

In practical dosing experience — including reports from advanced mushroom, SPS and trace-balanced systems — maintaining Rubidium within natural seawater levels has been linked with improved stability in coral response and recovery. For reefkeepers actively maintaining trace element levels rather than applying one-off corrections, supplement choice and purity matter.

Why Rubidium Matters

Rubidium is chemically related to potassium and is believed to contribute to ionic balance within coral tissue environments. In ICP-managed SPS/LPS systems and high-end soft coral setups (e.g. bounce mushrooms, discosomas, and similar species), maintaining appropriate Rubidium levels may support stronger trace consistency and environmental stability. As part of a complete trace-balancing regime, it is corrected based on ICP data and maintained incrementally over time.

Dosing Guidance

Oceamo Single Element Rubidium provides a precise and consistent dosing strength for safe, controlled ICP correction:

• 1 ml / 100 L = +5 µg/L (ppb)

• Maximum recommended increase: +25 µg/L per day (5 ml / 100 L)

Why Choose Oceamo Rubidium

• Designed for reefkeepers who actively maintain trace stability, not one-time corrections

• Pharmaceutical-grade purity, produced and batch-tested in Oceamo’s dedicated Austrian laboratory

• Trusted in structured ICP correction programmes and long-term SPS/LPS trace regimes

• Available in 250 ml and 1 L formats, making it significantly more economical for ongoing use than smaller entry-level bottles from alternative brands

• Part of Oceamo’s scientifically developed Single Element system, created by analytical chemists for measurable dosing confidence

When consistency, laboratory purity and long-term trace balance matter, Oceamo Rubidium delivers the confidence serious reefkeepers rely on.

Frequently Asked Questions

1. Do I need to dose rubidium in my reef tank?
   Only if ICP testing shows a deficit. It is typically required in SPS, LPS or advanced trace-managed systems over time rather than in casual or lightly stocked tanks.

2. Does rubidium improve coral colour or mushroom health?
   Some experienced reefkeepers report improved stability and response in corals such as SPS and high-end mushrooms when Rubidium levels are maintained within natural seawater ranges under ICP guidance. Results may vary depending on system conditions.

3. Why choose a larger bottle instead of a smaller trial size?
   Rubidium is often an element that requires repeat correction. For reefkeepers actively maintaining ICP stability, a 1 L pharmaceutical-grade source offers better long-term economy and reliability.
