Strontium is probably important for accelerating coral and calcareous algae growth. NSW (Natural Sea Water) contains approx. 7 - 9 mg/L strontium. This strontium is associated (”chelated”) with sulfate. Since the growth of corals and calcareous algae goes hand in hand with strontium and calcium depletion, depletion of calcium (which is very easily measurable) usually means depletion of strontium as well.
Strontium supplements should be designed in such a way that a too low or a too high strontium concentration is avoided. With Natural Strontium Salifert have reached this aim with an easy-to-use formulation. Salifert Natural Strontium contains predominantly strontium sulfate together with some other ingredients to avoid an ionic imbalance. This sulfate form is significantly more effective and less toxic than the commonly used strontium chloride. Furthermore strontium is present in natural sea water as the sulfate just like this supplement! Also, all ingredients are of a pharmaceutical quality or even better. This ensures that no unwanted elements are added to your valuable aquarium.
Dosage Salifert Natural Strontium:
Shake before use. Regular maintenance: Dose 5 ml per 100 liters of aquarium water (25 gallons) once a week or 2 weeks and adjust dosage according to individual requirements (use a strontium test). Every 5 ml per 10 litres of aquarium water (2.5 gallons) will increase the strontium concentration by approx. 2 mg/L (2 ppm). Maintain a strontium concentration of 5 - 20 mg/L.
