Salifert Iodine Test Kit

Get true iodine readings for the success of your reef aquarium. The Salifert Iodine Test Kit is the only test that measures all naturally occurring iodine compounds for accurate reading of total iodine concentration. Iodine in natural seawater occurs as several different forms including iodide, iodate, molecular iodine, and hypoiodite. Test kits unable to detect these forms will give a false, low iodine reading. Aquarium hobbyists who demand the best trust Salifert Iodine Test Kit for the ongoing health of their reef aquarium. For marine use only. 40 tests.

Range: 0.01 - 0.15ppm

• Rinse test vial before use with a little aquarium water. Then add 2 ml of water with the syringe.
• Add 6 drops of I2-3 reagent and swirl gently for 2-3 seconds after each drop.
• Exactly 4 minutes after adding this reagent compare colors with the iodide color chart. Hold the test vial firmly against the white portion of the color chart.

NOTE: Waiting longer than 4 minutes will cause further darkening of the colors. For color comparison use diffused daylight. Sometimes the colors can have a more yellow tinge depending on the color temperature of the light. If the color turns blue, purple, or black or a precipitate forms, then the iodide concentration is far above 0.2 ppm.

After each test rinse the test vial about ten times with tap or RO water.

Instructions for Iodate and Iodine Test:

• Rinse test vial before use with a little aquarium water. Then add 2 ml of water with the syringe.
• Add 1 drop of I2-2 reagent and swirl gently for 10 seconds.
• Add 6 drops of I2-3 reagent and swirl gently for 10 seconds. Allow it to stand for 3 minutes.
• Look from the side of the test vial. If the color is dark yellow, green or blue, or has several blue colored particles in it then this suggests that the iodate concentration is far higher than 0.2 ppm. As a result, an almost colorless solution with tiny blue particles (precipitates) might result in the next step.

  The next step will allow the measurement if the iodate concentration is not far above 0.2 ppm.

• Add 5 drops of I2-2 reagent and swirl gently for 10 seconds. Hold the test vial firmly against a white portion of the color chart. Compare colors with the Iodate color chart.

After each test rinse the test vial about ten times with tap or RO water.

Note:
The use of time released iodine supplements or supplements containing organically bound/complexed iodine will give false results.

The presence of strong reducing substances such as ascorbic acid will also give a false value. Some supplements do not contain ascorbic acid. De-chlorinators are also strong reducing substances.
