ASF Reef Shot – Strontium

Strontium Support for Coral Skeletal Growth & Reef Stability

ASF Reef Shot Strontium is a ready-to-use, single-dose strontium supplement formulated to restore and maintain proper strontium levels in reef aquariums.
Strontium works alongside calcium and magnesium in the formation of coral skeletons, playing a key role in SPS and LPS growth, skeletal density, and long-term reef stability.

In modern reef systems, strontium is gradually depleted through coral uptake, water changes, and filtration, making controlled supplementation beneficial in high-growth aquariums.

Key Benefits

• Targeted strontium supplementation for reef aquariums

• Supports coral skeletal formation and calcification

• Complements calcium and magnesium dosing

• Helps maintain long-term reef chemistry balance

• Single-dose vial (20 ml) for accuracy and consistency

• Ideal for SPS, LPS, and mixed reef systems

Directions for Use

• Shake well before use

• Dose 1 vial (20 ml) per 100 liters / 25 gallons

• Add once or twice per week, depending on system demand and test results

• Pour gently into a high-flow area of the aquarium

• Wait at least 5 minutes before adding any other product

• Do not mix with other products prior to dosing

A weekly 10–20% water change using a high-quality reef salt (such as Reef Evolution Salt) is strongly recommended to maintain balanced trace element levels.

Important Safety Information

• Avoid direct contact with marine organisms

• High localized concentrations may be harmful

• Do not overdose trace elements

• Keep out of reach of children

• For marine aquariums only

Francois Neo – AquariumPartner Insight

Strontium is most effective in high-growth reef systems where calcium consumption is already significant. Used responsibly and guided by testing, Reef Shot Strontium helps maintain strong coral skeletons without destabilizing reef chemistry.
