Salifert Profi Test Kits for reef, marine and advanced freshwater aquarists are some of the most precise and accurate test kits on the market. Kits are available for all aspects of the aquarium's chemistry, covering organic and inorganic pollutants as well as valuable marine trace elements to allow for accurate dosing when additives are required.
Strontium plays an important role by accelerating coral and calcareous algae growth.
Natural seawater contains approx. 7 – 9 mg/L strontium. Since the growth of corals and calcareous algae goes hand in hand with strontium and calcium depletion, depletion of calcium usually means depletion of strontium as well. It is advisable to maintain a strontium concentration between 5 and 20 mg/L.
Furthermore, natural seawater contains strontium associated with sulfate. This form lacks the toxicity, the commonly used, strontium chloride. The Salifert strontium test kit detects both ironically free and moderately complex strontium. Approximately 25 tests per kit. Measures in approx. 5 ppm increments.
