Oxygen test Salifert (O2) Oxygen is highly essential for all life forms. Especially corals and marine fish require oxygen concentrations at saturation level. This is because of the low solubility of oxygen in saline water which is approx. 5 - 7 ppm. The oxygen test measures oxygen concentration in just a few minutes. Approx. 50 tests per kit....

Iodine Test Salifert Iodine is present in NSW (Natural seawater) in a very low concentration (0.06 mg/L or 0.06 ppm). Iodine occurs as different species. Some of them are iodide, iodate and hypoiodite.

Potassium test Salifert

Strontium Test Salifert Strontium plays an important role by accelerating coral and calcareous algae growth. NSW 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.
