Fauna Marin Elementals Trace Se Selenium 250ml

Precision Selenium Supplementation for Reef Aquariums

Fauna Marin Elementals Trace Se is a concentrated, high-purity liquid selenium supplement developed to correct measured selenium deficiencies and maintain balanced trace element concentrations in marine reef aquariums.

Selenium is an essential micronutrient involved in antioxidant defence and cellular metabolism. Although required in extremely small quantities, it contributes to important biological processes in marine organisms.

Part of the Fauna Marin Elementals range, Trace Se provides precise, targeted supplementation for reef keepers managing individual trace elements through regular water analysis.

Key Features & Benefits

  • Targeted selenium supplementation – Corrects confirmed selenium deficiencies.

  • Supports antioxidant processes – Selenium is involved in important cellular defence mechanisms.

  • High-purity formulation – Stabilised selenium solution developed for marine aquariums.

  • Precise dosing – Suitable for carefully monitored, ICP-guided supplementation.

  • Ready-to-use liquid – No mixing or preparation required.

  • 250ml bottle – Concentrated formula for controlled trace element dosing.

Recommended Dosage

1ml per 100 litres increases selenium by 0.0005ppm (0.5µg/L).

Maximum daily increase: 0.001ppm (1µg/L).

This corresponds to a maximum of 2ml per 100 litres daily.

Always determine your aquarium's selenium requirements through suitable water analysis before supplementation.

Important Information

Selenium is required only in trace quantities. Excessive supplementation can be harmful to marine organisms.

Only dose when testing indicates a genuine requirement. Follow the manufacturer's instructions and avoid unnecessary additions.

For accurate trace element management, we recommend Fauna Marin ICP testing to help identify deficiencies and guide supplementation.

Keep out of reach of children. Store tightly closed at room temperature, protected from light.

Fauna Marin Elementals Trace Se – precise selenium supplementation for carefully monitored reef aquariums.
