Natural seawater (NSW) concentration of iodide is 0.06 mg/L. Ideally, it is advisable to maintain iodide close to NSW concentration. Concentrations above NSW may not be harmful, and, within limits, may even be benecial, but maintenance at elevated concentrations should be considered experimental.

The innovative MultiTest Iodine/Iodide kit offers a quantitative test for this important element of soft and hard coral growth. It measures iodine or iodide to less than 0.005 mg/L. The color scale peaks at 0.10 mg/L. It performs over 75 tests and contains a reference sample for validation.

• Catalysis based, sensitive to less than 0.0025 mg/L
• Multi-cavity plate for simultaneous testing of up to 6 tests at the same time
• Includes reference for test validation
• Marine or Freshwater
