Strontium is important for accelerating coral and calcareous algae growth. Salifert's Natural Strontium supplement is an easy to use formulation designed to avoid a too low or too high strontium concentration.
Natural Sea Water (NSW) contains approx. 7-9 mg/l strontium. This strontium is associated ("chelated") with sulphate. 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. Initial strontium concentration can easily be maintained by dosing the same amount as our Coral Calcium supplement. This reduces the need for a strontium measurement.
Salifert's Natural Strontium supplement contains predominantly strontium sulphate, 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 and is the form in which it is present in natural sea water.
The use of Coral Calcium as a calcium supplement is highly advised. In fact, for best results, Natural Strontium and Coral Calcium are designed to be used together.
