Reef Strontium 500 ml Seachem – strontium supplement for reef aquariums

Strontium is naturally present in seawater at a concentration of about 8 to 10 mg/L. Chemically similar to calcium, it is incorporated by many reef organisms into their calcareous structures, including corals, coralline algae, and tridacnid clams.

Reef Strontium is formulated to restore and maintain strontium at natural levels without altering the aquarium's pH. It uses a gluconate-complexed form of strontium, enhancing its bioavailability and limiting precipitation and alkalinity imbalance phenomena.

The gluconate used contains neither nitrogen nor phosphorus, which eliminates any direct risk of algae stimulation in a properly maintained reef aquarium.

Main Characteristics

Parameter Goals

The recommended strontium level in a reef aquarium is between 8 and 12 mg/L.

Usage Instructions

Beginner Level

Use 5 ml per 80 L of water, twice a week.

Advanced Level

Measure the strontium level, then follow the addition schedule above until reaching a concentration between 8 and 12 mg/L.

Each 5 ml dose per 80 L increases strontium by about 0.6 mg/L.

The quantity or frequency can be adjusted as needed to maintain a stable level.

Expert Level

After determining the actual strontium consumption of the tank, a continuous drip system can be implemented.

The quantity to add to the top-off water can be calculated using the following formula: m = 0.1 × v × s, where m corresponds to the product volume in ml, v to the tank volume in liters, and s to the desired increase in strontium in mg/L.

Example: to increase strontium by 2 mg/L in a 200 L aquarium, add 40 ml to the top-off water.

Important Considerations

Regularly test strontium using an appropriate test to avoid overdosing.

Significant adjustments should be made gradually.

An excess of strontium may increase the loss of carbonate alkalinity.

Do not mix directly with a carbonate supplement.
