Salifert Natural Iodine 250ml
Corals require iodine as a de-toxifier, as a protection against uv-radiation and as a natural defence against many parasites.
Salifert's Natural Iodine supplement contains iodate and also some iodide in similar proportions found in NSW. Both are present as their calcium and magnesium salts because Salifert's research has shown that iodate is complexed with calcium and magnesium in NSW. Another advantage of using these salts is that, unlike when potassium or sodium salts are used, no ionic imbalance is created.
Salifert stands alone in offering such an advanced, reliable and well thought-out formulation.
