Profi test Silicate allows you to monitor the silicates present in your marine aquarium. This product, in two solutions, allows you to perform 60 tests. Our opinion: Salifert tests are reliable and very affordable.

Silicate French WARNING

Keep out of reach of children! Do not swallow! Incorrect results can be obtained when the carbonate hardness is greater than 20 dKH. Normally, the carbonate hardness is much lower than this value.

INSTRUCTIONS:

1] Pour 1 ml of water into the test tube using the syringe.

2] Add 4 drops of Si-1 reagent, and gently swirl the test tube for 10 seconds. Let it sit for 5 minutes.

3] Add 4 drops of Si-2 reagent, and gently swirl the test tube for 10 seconds. Let it sit for 1 minute.

4] Add 1 spoon of Si-3 powder reagent, and gently swirl the test tube for 20 seconds.

5] Hold the test tube in front of you and look through it from the side. Hold the colorimetric scale behind the test tube. Ensure that a white part of the colorimetric scale is behind the liquid in the test tube. An intermediate color corresponds to an intermediate concentration.

LOW RESOLUTION: Place the open test tube above the colorimetric scale, on a white part, and compare the colors. Deduce the corresponding dissolved silica concentration. An intermediate color corresponds to an intermediate concentration.

NOTE: If the test was performed in low resolution, multiply the obtained value by 5. The values are in ppm (mg/L) of silica oxide. Avoid using tap water or osmosis water that contains more than 2 ppm of dissolved silica. In seawater, the dissolved silica content should be below the detection limits of this test.
