Versatile silicate test kit for sensitive and accurate test results. High quality test kit allows aquarists to measure silicate levels in fresh or saltwater aquariums. The Salifert Silicate Test Kit detects silicate in two different ranges. The high-range test is ideal for freshwater aquariums. The low range is designed for reef systems that require a sensitive test to detect low concentrations of silicate. Silicate can encourage brown algae (diatom) bloom in newly established marine aquariums and may block some essential trace elements, such as vanadium and molybdenum, necessary for healthy coral growth. The Salifert Silicate Test Kit is also useful to monitor the performance of your reverse osmosis unit. 60 tests. For freshwater and marine aquariums.
Range: 0.03 to 30 ppm
Erroneous results might be obtained when the carbonate hardness is higher than 20 dKH. This corresponds to an alkalinity of 7 meq/L. Normally, the carbonate hardness is well below the above mentioned values.
WARNING Keep out of reach of children. Not for consumption.
- Add with the syringe, 1 ml of water in the test vial.
- Add to this, 4 drops of Si-1 reagent and swirl the test vial gently for 10 seconds. Allow to stand for 5 minutes.
- Add to this, 4 drops of Si-2 reagent and swirl the contents gently for 10 seconds. Allow to stand for 1 minute.
- Add to this, 1 level scoop of Si-3 and swirl the test vial for 20 seconds.
- The color for the low range procedure has to be compared by looking through the SIDE of the test vial. The white part of the color chart has to be held firmly against the opposite side of the test vial. Use diffuse daylight when comparing colors. An intermediate color corresponds to intermediate dissolved silicon content. The silicate values are in ppm (mg/L) silicon oxide.
- If the value is higher than 1 ppm, the range can be extended by placing the test vial on the color chart on a part of the chart, which is white, and by comparing the colors by looking from above. If the colors are compared looking from above, then the color chart value has to be multiplied by 5, thus extending the range from the initial 3 ppm to 15 ppm
Avoid using tap water or RO water, which contains more than 2 ppm dissolved silicon.
In marine water, the dissolved silicon content should be below the detection limit of this test.
