Profi Test Silicate Salifert – Si Test for Reef Aquarium

The Profi Test Silicate Salifert allows you to monitor the concentration of silicates (Si) in a saltwater aquarium. Silicates are mainly responsible for the appearance of brown algae of the diatom type, especially when starting a reef aquarium or in case of poor quality osmosis water.

This test works with several reagents and allows for approximately 60 tests. Salifert tests are known for their reliability, accuracy, and excellent value for money.

Main Features

• Test type: silicates (Si)
• Use: marine and reef aquarium
• Number of tests: approximately 60
• Reading by colorimetric comparison

Safety Information

Caution. Keep out of reach of children. Do not ingest.

Erroneous results may be obtained when the carbonate hardness exceeds 20 dKH. In marine aquariums, the carbonate hardness is normally well below this value.

Instructions for Use

1. Pour 1 ml of water to be tested into the test tube using the syringe.

2. Add 4 drops of reagent Si-1, then gently stir for 10 seconds. Let it rest for 5 minutes.

3. Add 4 drops of reagent Si-2, then gently stir for 10 seconds. Let it rest for 1 minute.

4. Add 1 spoonful of powder reagent Si-3 and gently stir for 20 seconds.

5. Hold the test tube facing you and observe the color from the side. Place the colorimetric scale behind the test tube ensuring a white area is behind the liquid. An intermediate color corresponds to an intermediate concentration.

Low Resolution Mode

For a low-resolution reading, place the open test tube above the colorimetric scale on a white surface and compare the colors. An intermediate color corresponds to an intermediate concentration.

If the test is conducted in low resolution, multiply the obtained value by 5. The values are expressed in ppm (mg/L) of silicon dioxide.

Usage Tips

Avoid using tap water or osmosis water containing more than 2 ppm of dissolved silica. In a saltwater aquarium, the concentration of dissolved silica should normally remain below the detection limits of this test.

Regular monitoring of silicates effectively prevents the appearance of diatoms and ensures optimal water quality for corals and fish.
